They would have to sit back, tell their client to plead the 5th, and let the prosecutor do their job of proving a crime was committed by the suspect beyond reasonable doubt.

I watched the OJ Simpson trial when I was a kid. I was sure he was guilty. I think his lawyers thought so as well. Once they realized the LAPD had tampered with the crime scene and the evidence they used that wedge to open the door for reasonable doubt. And they absolutely hammered at it for months. By the end the jury was full of doubt.

Most public defenders don't have the resources for that kind of defense. And most assume their client is guilty. Which is why plea bargains are prevalent.

An alternate explanation for the prevalence of plea bargains is that many defendants are actually guilty of something, that guilt is likely enough provable to not be worth the risk, and we’ve allowed sentencing guidelines and charge-stacking practices to amplify that risk to the point where it’s game theoretic sensible to take a light plea deal. I’m not nearly convinced that public defender assumption of guilt is a significant driving factor.

Unfortunately, there are reasons to accept a plea bargain even if you are perfectly innocent.

First, reality is not important per se, only how the judge and the jury see it. If you know you didn't do something, but there is evidence pointing towards you, and you have a reason to believe that people judging you would be convinced by it... it makes sense to accept a smaller punishment (for something you didn't do) rather than risk years of prison (for something you didn't do).

Second, the process itself is already a punishment. How many times can you be absent from your job because you are at the court, before you lose the job? How much will it cost you to pay for the lawyer, for travel, etc. If you are poor, it can make more sense to accept a smaller punishment for something you didn't do, rather than ruin your life in an attempt to prove your innocence.
