Screw Chief Inspector Fish & the public that he claims expect the police to salve their consciences by keeping the wretched from public view.
If a police officer grabbed, say, a bag or purse from most citizens & either kept or disposed of it (even as part of a legitimate arrest) the officer would be punished at least a little, you know, if someone who gave a shit found out. But grabbing anything belonging to rough sleepers & doing whatever w/ it is a legitimate police function. (Apparently transients are allowed to have as much property as they can keep in their arms.*) No house, no money, no power, no rights.
*Would be a good thing if applied to every last one of you fucking apes.
