IAAL in fact I'm a DA. So let me give you some perspective from the other side. If a prosecutor is doing his/her job then if they don't believe someone committed a crime or even if they don't believe there is a likelihood of conviction then they must dismiss the case. I am most proud of the times I have dismissed cases where through further investigatory work or an honest evaluation of the case I found I could not in good conscience proceed. I would hold out my dismissals as some of my greatest achievements even over my convictions of extremely dangerous and evil murderers and rapists. Why is this? Because as a prosecutor you have the ultimate discretion on whether to proceed and your decision is paramount in its effect on peoples lives. My greatest fear would be to prosecute an innocent man but as a prosecutor with morals and who never just settles for taking someone's word for it (unless there word is corroborated by extrinsic evidence) I dig and use my own investigators and review the forensic evidence until I'm satisfied I have the guilty party. Therefore, it is very unlikely for me to convict an innocent person (short of a perfectly executed set up that is near impossible despite what the media would have you believe) especially since I have dismissed cases where I didn't believe the defendant committed the crime or when I didn't believe I could secure a conviction. I sometimes joked with a defense attorney colleague of mine, "if your guy is truly innocent I'm your favorite DA but conversely if your guy did it look out because I'm coming for him/her come hell or high water!" She agreed with my assessment. Now the problem is not every DA is like this, some are in the job just to make their trial bones and then get to the defense side some are lazy and just looking for the paycheck and will use the stiff sentence or habitual counts as a hammer just because they don't want to do the work. But there are a cadre of career prosecutors who like me do it for the right reasons and live up to the higher standards reserved for those who protect the People. I have never minded someone demanding a trial as I enjoyed the process but there is something to be said where the defendant delights in re-victimizing the victim. I once had to sit a watch as a defendant's attorney at his direction cross-examined a sexual assault victim not once not twice but three times due to mistrials and misconduct by the defense and he throughly enjoyed the hell he put her through on each occasion. (on a side note he tied her up cut her clothes off with a knife, held a gun to her head broke her jaw and nose, and then tortured her sexually). We had the evidence from the start and even though there always is the possibility of an acquittal there should be a punitive penalty for exercising your rights when in doing so this type of harm occurs. (second side note the judge witnessed how much the defendant delighted in the pain he both initially caused and the subsequently caused to the victim during the trial and he was sentenced to 48-life in Dept of Corrections. By in large most of my cases are not even close when it comes to guilt or innocence, its just a matter of considering all the factors and coming up with an appropriate plea based on criminal history, age, impact of crime and community safety. I often wonder what would happen if the defense could convince a large majority to demand trials (this would have to be public defenders as most who retain private attys couldn't afford to go to trial) what would happen? The result would be many lower level criminals would get more substantial sentences while taking away prosecutors ability to adequately attend to serious criminals so as a byproduct inevitability some cases where further work and investigation would be necessary to secure a conviction guilty defendants would go free and continue to hurt those we seek to protect causing more victimization and pain to those who are least able to protect themselves. Sorry for the verbosity of my post but I obviously feel strongly about this issue.
