Oh yeah, I've witnessed it. An ADA held a known unsupported charge that carried pretrial restrictions only found under that charge. Then they prevented us from talking to court scheduling to secure remote accommodations for a witness (so they couldn't testify) - even though the rules of procedure/discovery didn't allow them to do that for a summary case, and violated the Bar's rules of professional conduct. I filed a complaint with the Bar. The Bar didn't even look at it. They did they'll only investigate after a court formally declares that prosecutorial misconduct occurred. Ok... so what do you actually investigate if the determination has to already be made?
