Sounds like a job for the Texas National Guard
They aren't hitting gangs or any actually dangerous people, they are looking for weak targets. They aren't trying to clean up the streets, they are geting their rocks off playing GTA IRL.
Unfortunately homelessness is something that can't be solved by one city or even one state. Feeding, housing, and getting them treatment is expensive and not something even the wealthier cities have the budget to do on their own. And the first major city that tries will have to deal with other places dropping more homeless people on their doorstep - that's one thing that both red and blue cities have been guilty of as you can read about at https://www.theguardian.com/us-news/ng-interactive/2017/dec/...
Seems a contradiction.
They're usually harmless, just troubled. You're not in much danger walking down the street; you're actually in much more danger driving down it.
There is a big difference between feeling uncomfortable and being in a genuinely unsafe situation, and the less you are used to seeing the homeless, the more out of touch with reality your gut feelings are.
Doubly doubtful for the following reason: these people need the problems to exist, so that they can write their narrative around them, and offer their "solutions" for them. Same as how cults target vulnerable people.
