Ignoring the personal attacks and hyperbole in your post: In a system without government prosecutors who do you think should prosecute for crimes? Should a murder victims family have to hire a private attorney to file a civil lawsuit? If they can't afford it, will the murderer go free? Please think your argument through to the end before taking cheap shots against the government in general.
