This kind of stuff really annoys me!
If there was ever a reason for NOT having a system where we give housing away to lazy people this would be why, I bet 99% of chavs come from a background where parents won't work and social housing is a guarantee, how are there children meant to learn how to be a responsible person? its a perpetual cycle. Hopefully with Labour and there socialist agendas out the way we might be able to move on and instil responsibly back into people.
Yes America, here in the UK if you decide you don't like working you get a house for free! hows that for bat-shit-crazy!
To the OP, I'm glad your brother is Ok, it sounds like a horrible experience to go through! lets hope they find these thugs and imprison them, but I expect with our present criminal justice system they will only get a couple of hours of community service . . .
