My impression....there’s no law to prevent vagrancy, but the police tend see the individual just loitering around, and then start asking questions. If you show alcohol or drug issues...you get picked-up and taken to the station. If you seem a bit unbalanced, you get a ride to a clinic to be examined. I’d just say they are more proactive than anyplace I’ve ever been.
I didn’t see the tail end of this but I would imagine there’s some fenced-in facility where you might remain a couple of weeks or months.
The way it used to be here.
