Yeah, fantasies about crime and justice play well here...and we all have them. But the USA isn't a libertarian Disneyland, and I don't think the Founding Fathers ever intended it to be one.
In a legislative hearing or a meeting with elected/appointed government officials, you have to present rational and reasonable arguments to people who might not be inclined to agree with you, and then persuade them to vote your way.
