> I do not live in one of the cities that have issues with a large homeless population, so the experience is a bit lost on me
That's the key experience you're missing. If you've never lived in a high-homeless/drug abuse area, you don't really understand how thoroughly draining it is on every aspect of civic life.
I live in DC and do not wish for human rights violations against these people because they bother me. I understand how draining it is but IMO forcing us all into a surveillance state because of "undesirables" is the laziest way to solve this problem.
So the answer to a problem the police and authorities already know about is a surveillance state for everyone? How are ever more cameras going to fix the drug abuse/homlessness problem?
I recognize that I'm missing that part of the context, but it still surprises me that the answer to that is relatively global surveillance. In the current state of things, homelessness is perfectly public and observable, right? And so at any point now, the proposed "enforcement" could take place without the need for cameras? I think that part is unclear to me as well, the problem that exists that this solves.
