CW Nevius at the SanFran Chron: 
San Francisco – the liberal, left-coast city conservatives love to mock – could be undergoing a transformation when it comes to homeless people. Although the city would still be a poor choice for a pep rally for the war in Iraq, indications are that residents have had it with aggressive panhandlers, street squatters and drug users.
Well, it’s not a full turnaround, but one step at a time.
The thing that worries me about this is they were successful in learning their lesson only after the aggressive homeless types came along with a somewhat ratty 2*4 and whooped them upside the head with it. Wow. Reality. What a concept!
One would hope that they learn the reality of the Iraq war situation before someone shouting “Allah Akbar” (Boom) gets to teach them on the point.
