There might be some improvement, but how much can be gained by shuffling things around? The U.S. is a democracy and prosecutors are aggressive because it's what the people want. If we shift that power to a local executive, committing to nominate hardline prosecutors will become a typical campaign promise (similar to our current situation with presidents and supreme court justices). I think the only real fix is education.
