its very interesting that the unfortunate people who sleep rough in shop doorways are tolerated, simply because if they were arrested (for trespassing,etc) they would need to be housed for the night either in a hostel or police cell, and that means money would have to be spent, yet a couple of folks who throw up a tent or hammock are usually chased , and threatened with being chatrged with trespassing, here in Cornwall it was estimated there was 3500 homeless over the Christmas yet there are thousands of empty caravans on sites here as well as empty second homes.
