There's also the matter of the use of public funds to prosecute someone. A good prosecutor shouldn't need 'backup' cases to get a conviction if the case is strong. Keeping victims 'in reserve' in case of legal screwup would also mean spending beaucoup public bucks. It's also ethically problematic to tell some victims, "you don't get justice for your crimes now, but justice will be served for you by proxy, and if we need another trial, you'll get your chance."
