This isn't Minnesota or New York City. Our winters are mild; you don't need meth to stay warm at night, and the transients here tend to have more than enough clothing to stay warm when it gets into the low 50s/40s.
In fact this mild weather is probably why we have so many of them literally dumped on us. (Dumped, as in, given a one-way ticket to a sunny, seaside city of their choice)
Community policing programs work, just look at the success that Urban Alchemy has had in Los Angeles and San Francisco. The community is more than capable of policing itself, but it doesn't.
With respect, do you believe people choose to become addicts?
I'm not talking about opoids which were sold to folks as non-habit-forming for a long time. Or other cases of addiction without consent. But I don't think that is the case here, for the majority of people.
