I'm personally not into incarcerating mass amounts of people, as it only centralizes a prison industrial complex. Rather, one glaring issue is dangerous drugs showing up on our streets & the conditions that lead to this usage. In the comment you linked to, I noted Kensington Ave in Philadelphia, where there are videos of many people on hard drugs stooped over. Many people, who would otherwise have happier lives are now dealing with addiction & living on the streets. Note that the reason why drugs are showing up on the streets are not random acts of mere petty criminals but involve people in domestic government & foreign governments. Rick Ross & the crack epidemic detail the history of how intelligence agencies create the conditions of mass addiction.
While some, including me, think this drug problem is an example of the hypocrisy of NeoLiberalism...I also think it's a centuries old playbook of wreaking havoc on whole populations of people by introducing vices such as drugs. The Opium Wars & what lead to the Opium Wars is an example.
Side note, I would like there to be a graph based form of communication that can better express the context of statements. It's too easy to take a couple of sentences on a forum out of context.
