go to the local library in Tuscon they should have a state legal newspaper in those legal papers they will usually list the most recent jury awards and the lawyers who won those awards as well as the amount awarded , that's a start
Legal ethics are different than normal ethics. The function of a defense attorney is not to promote justice for society. The function is to ensure that the defendant receives a fair trial. And if the police violated the defendant's constitutional rights - then any evidence/confessions, etc. that were obtained illegally gets tossed out. (And without evidence, it becomes awfully difficult to secure a conviction.)
And I don't know of any criminal defense attorney who even WANTS an innocent client. It's too much pressure - and you feel like crap when your client gets convicted. I do only a tiny amount of criminal law - and I only represent clients who are guilty and who are admitting they are guilty in order to obtain deferred adjudication. If they are innocent and want to go to trial, I refer them.
Prosecutors who don't have a legitimate basis to believe the defendant is guilty of the crime for which s/he is being charged face disciplinary action up to and including being disbarred. No attorney is allowed to file a frivolous court case.
