Why AI Legal Advice Can’t Replace a Criminal Defense Attorney

AI gave you the answer. But is it the right answer for your legal problem?

AI will give you immediate answers, clear, confident explanations, and a warm, fuzzy feeling. It’s free or close to free, and it’s convenient. 

It even feels private.

But GenAI tools may give you bad legal advice. If you’re facing criminal charges in Placer County, CA, or Nevada County, CA, or any county for that matter, relying only on AI chatbots can leave you facing serious consequences.

Does AI ever provide helpful legal information?

AI programs like ChatGPT, Claude, and Gemini are not really “Artificial Intelligence.” They’re more like highly advanced predictive engines that draw on a vast body of online knowledge. 

They are useless for anything that requires real judgment, but can be useful for some legal tasks.

Use AI to:

• Understand legal terminology
• Learn the general court process that might govern your case
• Get a high-level overview of potential penalties for specific criminal problems 

If you want advice that goes any deeper than that, AI-generated content will not help you.

Here’s what AI can’t do to help you with your legal issue

• It cannot evaluate the specific facts of your case. It may try to do so, but you can’t rely on its accuracy, and what it doesn’t know can hurt you.
• It will not have any specific details about your jurisdiction. The lived reality of a case can change a great deal between counties. Different judges handle things differently. AI does not know this and can’t know this: it’s a matter of boots-on-the-ground experience.
• Discretion plays a big role in our justice system, especially prosecutorial discretion. AI cannot predict how any given prosecutor will react to an attempt to get charges dropped, dismissed, or reduced. 
• AI cannot predict long-term consequences.

Why is using AI for your legal issue risky?

AI can result in you:

• Getting overwhelmed—it’s easy to bury yourself in irrelevant information. 
• Wasting time—you might spend a lot of time spinning your wheels or missing important deadlines when you’d have been better off calling an attorney instead. 
• Coming up with citations that don’t exist or pulling cases that do not have controlling authority…and if you tell your lawyer to try to chase them down, you’ll end up paying more.
• Missing consequences. AI oversimplifies. It may tell you that your case isn’t serious, but it may not be taking into account the fact that you can lose custody of your children, the right to bear firearms, or your professional license. Had you known, you might have hired a lawyer… but you didn’t because you asked AI. 

AI is free…but remember, our initial consultation is free too. You can get a lot of information during our consultation, and the cost to defend your case might not be as scary as you think. You won’t know until you ask. If you truly cannot pay, the California courts may appoint a Public Defender to represent you. 

Here at the Cohen Defense Group, we’re not anti-AI. It has its place and its purpose. It’s new and getting better every day. But it cannot serve as a substitute for a good criminal defense attorney.

• It cannot stand in the courtroom for you and speak on your behalf.
• It won’t negotiate with the prosecutor. 
• It doesn’t have relationships with prosecutors and judges.
• It doesn’t know the little nuances of how a case may play out in Placer County vs. Nevada County. 
• It cannot effectively evaluate the specific, unique facts of your case.
• You are not protected when you use AI: your interaction is not covered by attorney-client privilege, which could mean the difference between going to jail and remaining free.

AI assists Cohen Defense lawyers. It does not make decisions.

AI is used as a starting point, not a final answer.

It does not make decisions or determine strategy. Every result it provides is reviewed, verified, and analyzed by an attorney. We interpret the law and apply it to the specific facts of your case.

AI can surface information, but it cannot determine what matters or how your case should be handled. That requires legal judgment.

Why human oversight is critical for lawyers using AI

Legal work is not just about finding information. It requires understanding nuance, interpreting facts in context, and making strategic decisions.

AI cannot assess credibility, anticipate how a judge or prosecutor will react, or make judgment calls based on experience. Those are the factors that often determine the outcome of a case.

AI doesn’t change our ethical and professional responsibility to you

Attorneys are ethically required to ensure accuracy and protect client confidentiality.

That means we do not rely blindly on AI output. We independently confirm and analyze all information before using it in your case.

If something is wrong, we are responsible, not the software.

The difference between our use of AI as lawyers and the general public’s use of AI

Many people enter personal legal details into AI chatbots and rely on the answers without verification.

That creates real risk. The answers may be wrong, and these platforms are not protected by attorney-client privilege, so what you share may not be confidential and can be used against you.

Our use of AI is controlled. We do not rely on it blindly, and we independently confirm and professionally analyze all information. We do not rely on it to make decisions. Our use of AI helps with efficiency in your case, but it does not replace our legal expertise and judgment.

Where can AI legal advice go wrong in criminal cases?

AI only answers the questions that have been asked.

A lawyer identifies all the risks you might not think to ask AI about at all.

A case isn’t just about the law. It’s about:

• Meeting strict deadlines
• Local filing practices
• Prosecutorial discretion
• Diversion options
• Evidentiary weaknesses
• Collateral consequences beyond the criminal case
• Early decisions that shape the direction of a case

For example, in Tahoe City, a commissioner usually oversees criminal matters, and retired judges may rotate in when needed. In Truckee, a judge hears the cases. Each of these officials makes their decisions very differently. AI will not know how to turn these differences to your advantage. 

In Placer County, judges frequently rotate between departments, and retired judges are often brought in to assist with calendars. The court is also increasingly utilizing commissioners in criminal matters. At Placer County Superior Court, this means that the approach to a case can vary significantly depending on who is presiding on a given day. Each judge or commissioner may have different expectations when it comes to negotiation, motion practice, and courtroom procedure. An experienced attorney learns how different judges prefer cases to be presented, when a case may benefit from being set for a hearing versus resolved early, and how to adjust strategy depending on who is on the bench. AI cannot track or apply these constantly shifting dynamics. 

In contrast, Sacramento County tends to have more consistency in judicial assignments, with judges typically remaining in the same department. At Sacramento County Superior Court, that consistency means each courtroom develops its own expectations, preferences, and patterns over time. Judges often have specific ways they like motions argued, cases negotiated, and issues presented. Through repeated appearances, attorneys begin to recognize which prosecutors are more collaborative, which cases require a more strategic or persistent approach, and how to tailor arguments to a particular department’s tendencies. AI does not have access to these relationships, patterns, or practical insights.

These are the kinds of details that aren’t written in any statute or case law, but they can significantly impact the outcome of a case.

Example #1 of where AI legal advice can go wrong: AI asks the wrong questions

Our client, “Amy,” was a passenger in a car. The driver was on probation. Amy was not.

Police stopped and searched the car. There were drugs in plain view in the middle console. Both Amy and the driver had access to the drugs. 

Amy felt the search was illegal, but she was wrong. The search was legal because the driver was on probation.

Amy asked AI. AI said, “Don’t get out of the car, they can’t ask you to do that.”

But the police absolutely had the right to do that. Amy didn’t tell AI that she was driving with someone on probation. She only told the chatbot about herself, not the driver. The result: bad advice. 

Because Amy didn’t get out of the car, she got into deeper trouble than she would have if she had complied with police instructions. 

We were able to help Amy, but this is a great example of a case where AI could have led to additional charges rather than helping Amy as she’d hoped. 

Example #2 of where AI legal advice can go wrong: AI sends a veteran to the wrong court 

Our client, “James”, was a military veteran who was facing domestic violence charges. 

AI told James to enter a plea and go through veteran’s treatment court. 

If he had followed AI’s advice, he would have entered a plea deal he never needed to enter. 

Instead, he called me. I was able to show the District Attorney (DA) that the alleged victim was making everything up. We were able to provide air-tight evidence that she was the initial aggressor. We asked the DA not to ruin this man’s life with a bad case. The DA used discretion to drop the whole thing, all because I was able to provide information the DA didn’t have at the time of charging. 

It’s a stark example of how a lawyer can make everything better.

At least the AI did one thing right. It referred James to our office. 

Here’s what James had to say.

“Angel Sanchez and Cohen Defense were the attorneys I was looking for. After being arrested, I didn’t know who to turn to. After my service in the military, I barely trust civilians to do right by me. I used AI to analyze court cases similar to mine and had it find me the best attorney who specializes in veterans’ issues. It suggested Cohen Defense Group and the AI was absolutely correct. The awards on their wall speak for themselves when entering their office. From the moment Mr. Cohen answered my text, I felt assured I had the right place. Angel Sanchez was assigned to my case. I felt she was the right attorney, based on her background, and after the conversations I had with her. From the moment she accepted me as her client, I felt at ease, and I felt things could go in the right direction. The case ended up going in the direction I hoped for. I do know it’s because the DA saw I had support from Cohen Defense Group and Angel Sanchez. I keep telling myself ‘if you hired any other attorney than Angel, I don’t think the outcome would have been the same.'”

Note that if you’re a veteran, there are two types of veteran’s courts. There is a veteran’s treatment court and a military diversion court. AI doesn’t seem to understand the difference, in part because not much information is published about it. 

We have had other clients tell us that they wanted to do veteran’s treatment court, simply because they are a vet. But in some cases, military diversion is better, because it allows for pre-plea action. A veteran can really harm their interests by following AI advice to enter a plea. 

Example #3 of where AI legal advice can go wrong: AI got the statute of limitations wrong 

One client used ChatGPT to try to figure out when the statute of limitations was up for a potential misdemeanor battery charge. He hadn’t heard anything, so he assumed nothing had been filed.

He called Cohen Defense Group to expunge the incident.

He was surprised to find out there was a warrant out for his arrest because the case had been filed a few months prior, and he inadvertently missed the court date. It’s possible a notice got lost in the mail or was never sent. Had he not called us, he could have been stopped for a traffic ticket and ended up behind bars due to this warrant. 

We were able to call a bail bond agent on his behalf to see what the bail would be so that he could get everything lined up before he turned himself in to clear the warrant. That was all in an initial consult, and it was the consult that kept him out of jail.

Example #4 of where AI legal advice can go wrong: it increases your costs

Some clients become so confident in AI research that they end up costing themselves time and money by bringing in case law, statutes, and citations that do not actually exist.

They come in thinking they have a great case and that all the charges should be thrown out.

As a lawyer, I can’t just tell you that you’re wrong on the spot. I’d be violating my own professional duty and ethics.

I have to read every page of the case law to make sure I didn’t miss anything and that I understand what you’re talking about. That’s time you, as a client, end up having to pay for. Some laws take precedence over others. AI can’t seem to understand this. Lawyers know. 

Worse than that, we just feel bad when we have to tell you that this thing you’re hopeful about doesn’t apply in your case because of some tiny detail you forgot to share with AI, or because the AI didn’t realize what mattered, or just plain hallucinated.

Where can AI go wrong about professional licensing issues in your criminal case?

Many professional licenses come with reporting requirements. If you fail to let the licensing board know about the charges you’re facing in a timely fashion, you can end up being penalized just for failing to report! 

You need an attorney to research these requirements for you, because every board is different, and so are the crimes you have to report. 

For example, some boards don’t require you to report being charged with a DUI, but if that DUI also came with a hit-and-run charge, they absolutely do. 

AI will not always know what you do or do not need to report. 

One small decision can lead to many problems down the line. 

Example of AI being wrong about professional licensing: a nurse’s career at risk

One of our clients was a nurse who was in danger of losing his license. He was charged with public exposure for gratification.

Our office was able to bargain with the District Attorney (DA), and the charge was reduced to a disorderly conduct charge. We then helped our client enroll in mitigation measures, softening the blow and giving him a fighting chance in front of the nursing board. We shared all of this with his licensing defense attorney, who was able to save the client’s license. 

Imagine if the nurse hadn’t come to us and had gone to AI instead. He may have been convicted of the more serious charge and could have been fired from his job. This charge would have come up again and again on background checks. He would’ve lost everything. Instead, we negotiated a favorable resolution, and even got the plea withdrawn, an early dismissal, and had the case sealed, which helped tremendously during his licensing board hearing. He retained his license and returned to work a little wiser for the wear. 

Things you should never share with AI about your criminal case

NEVER tell AI the following:

• The specific facts of your case. It won’t get you better advice, and it means the prosecutor can use those facts against you.
• Any admission of wrongdoing.
• Any description of your lawyer’s legal strategy—AI can’t evaluate that for you or serve as any kind of a second opinion. 
• Any information from your attorney.
• Any details: names, dates, identifying details. 
• Any documents, such as police reports. 

AI is not your friend. AI is not your lawyer. And unlike lawyers, AI programs are not bound by ethical and professional responsibility to ensure accuracy and protect confidentiality.

You will be tempted. You will want reassurance throughout your case. The chatbot is right there at 3 in the morning. Please do everything in your power to resist the urge. Doing so could be the difference between years in jail and a short diversion program that leaves you free and your record cleared. 

Does AI know how much a lawyer costs?

No. If AI told you a number, it’s taking a guess.

Legal prices are rarely set. They are based on:

• The lawyer’s knowledge and experience
• The complexity of the case 
• The type of billing the lawyer uses
• Whether you’re calling pre-charge
• Whether a trial is likely 

If you want accurate pricing, consider calling attorneys and getting quotes.

AI only knows what is published online. Few attorneys publish their rates online, and every case is unique, so AI cannot give you a valid answer. 

AI can’t predict what will really happen in your criminal case

AI may be a predictive engine, but it predicts text, not case outcomes. 

• You may forget to tell AI vital details.
• AI may not know what those details mean.
• AI does not ask good follow-up questions.
• AI forgets about collateral damage like the loss of professional licenses.
• AI does not know the local District Attorney (DA).
• AI does not know the judge.
• AI does not have your attorney’s negotiation skills.

Even a good attorney can’t predict your case with 100% certainty. Don’t rely on AI to do it for you. 

AI cannot account for things that can make or break criminal cases

For example:

• Local filing practices 
• Diversion options
• Informal negotiation opportunities
• Evidentiary weaknesses that may influence charging decisions
• The strategic value of early intervention

AI can’t represent you pre-charge

If you involve attorneys early, we can:

• Present mitigating evidence
• Influence filing decisions
• Potentially reduce charges
• Sometimes secure diversion before formal charging

AI cannot negotiate, intervene, or assess local discretionary patterns. 

AI can’t help you avoid charges before they are filed

Attorneys who come into the case before charges are filed (pre-charging) can take action to avoid filing or to get lesser charges filed. 

AI can’t help with this.

Pre-charge work requires investigation, evidence gathering, and conversations with local district attorneys.

AI told me to wait to see if charges are filed – should I?

Absolutely not, even if you think AI is telling you some pretty convincing things.

Always, always contact a lawyer right away if you want the best possible outcome for your situation! 

AI can inform you, but it cannot defend you

AI can only provide general information. 

It cannot:

Manage critical deadlines

• Evaluate local filing practices
• Predict discretionary decisions
• Identify overlapping collateral consequences
• Intervene strategically on a client’s behalf
• Represent you pre-charging

In time-sensitive or high-impact cases, legal guidance can change outcomes. 

A free consultation with an attorney will give you more thorough and accurate information than an AI search, and may even be all that you need.
