This is wrong. No amount of toxic individualism is going to make someone cross the Rubicon of using extreme violence (ie: shooting someone). Maybe non-violent theft but the US has serious violence issues.

People who use extreme violence against other people are deranged. It's a mental health issue. In other countries, it's limited and so the heuristic is to just lock these people up in some place called prison. In the US it's endemic making it difficult to control no matter how many people you are incarcerating.
