Two professionals meet at a street corner in downtown Victoria. They set their laptop cases down and begin to talk to each other. One of them leans against the wall of a building. Suddenly two police officers arrive and start yelling obscenities at them. They point out a no loitering sign in the window of a nearby restaurant and while one officer demands identification and issues trespassing tickets, the other confiscates their laptops as abandoned property and throws them in the trunk of a police cruiser.
Does that sound familiar? Of course not. This type of thing would never happen to people who look like consumers or property owners. If you read that paragraph again, replace "'professionals"' with "'homeless people."' It makes much more sense now.
