I agree about the prosecutors. Some defense attorneys, however, are just as bad as the prosecutors, and don't want to "upset" the judge (who hears all their cases) or the prosecution (with whom they have to work, and who might REALLY stick it to their next client) by putting up too good of a defense for a client who is unpopular (ie, rich, white, professional). The defense attorneys are in on the "game", some of them.
You are absolutely correct. Too many defense attorneys, even the privately retained ones sellout their clients because they are too lazy and want to get along with the judges and prosecutors. Then there are those defense attorneys, a few in every county, whose clients seem to have their criminal charges dropped for technical reasons or are somehow simply never brought to trial and later the charges are quietly dismissed. Steve Thayer in Clark County is a perfect example, except if the prosecutor and judges want a conviction for political reasons.
In my situation, I caught a visiting judge, hand-picked of course, who committed perjury during a hearing. I forced the sheriff to investigate it; the opponents attorney agreed that the judge lied from the bench, the sheriff referred it to the prosecutor; and even thought the judges name is all over the report; the named suspect is "Last name: None; First name: None." True story! BTW, the other party was the sheriff, so he knew the prosecutor wasn't going to prosecute anyway.
