The prosecutors I know are too busy working to try to convict the innocent. Besides, appeals that are lost make them look even worse. Most prosecutors follow the law, follow the rules, and look seriously at the evidence. If they have no case, they will not proceed.
Sure, there are bad apples, but that usually involves politically motivated assholes who use the prosecutor's office as a means to gain some elected office. Luckily, that is a rare few.
