The problem with "getting your hands dirty" is that you're positively not prepared to take it through to it's logical conclusion. Shooting a burglar in self-defense works as long as burglars are rare and generally on the run from police. You shoot a burglar in a place where burglars are able to operate openly, their gang comes back and murders your family.

If you ARE prepared to take it to it's logical conclusion, you're not really a normal person, you're more like <picture>.

If you want to be a normal human being, you want to live in a place where you will not meet a violent criminal and that's that. BUT, people who live in soft conditions become soft, and they end up voting for soft politicians who make soft decisions which lead to actual hard times, this is an unsolved problem.
