> You aren't more deserving of punishment for being stupid.

I was being tongue in cheek. Punishments should fit crimes and those accused should not be judged on the basis of intelligence, race, wealth, or any other factor but the facts of their case. That said, it's easy to prosecute cases with abundant evidence available. Such crimes tend not to be premeditated, and easy convictions serve as social reenforcement to deter similar crimes.

> The criminal justice system has serious flaws and I'd rather not be wrongly implicated just because I happened to shed DNA near where a crime happened.

Fair point.

DNA should be used to place persons at crime scenes and not be used in absence of additional evidence. Unless said DNA was found on the victim of a sex crime, under fingernails, etc.
