The solution is to not tolerate drug use, petty crime, vagrancy etc etc

Homeless people aren't stupid. They find a way to get to where it is most comfortable to be homeless. In SF you can do drugs all day and night and get free needles and poop on the streets and no one will bother you. In other places you will not be able to do this.

Why are people surprised that places that go to great expense to subsidize homelessness have a lot of homeless people?

If we're talking about 'reasonable' conservatives, the typical answer is that booking people who commit a crime, and then using the threat of prison time to force them into rehab will ultimately be much better for them and the community than immediately releasing them under the guise that poverty causes addiction and crime and that therefore they are essentially blameless.

Some former addicts attest that, when they were addicted, it was only the threat of prison time that could force them into rehab, because at the time they were not fully in control of their own decision making. They say the 'stick' helps motivate them to choose rehab instead, and it ultimately helped them out of a bad situation.

Sam Quinones' book, The Least of Us, documents some of this and is well-researched.

Being the shitter.

Enforcing the law.

The conservative solution is to move to a place where they arrest the poopers.

Who said homelessnesses and mental illness have solutions?

Shitting in front of liberals' homes to convert them into conservatives.

Blaming liberals.
