Cameron cut them off the 'dole'; reduced social service spending to reduce the debt/deficit spending is what I read as the real background. "Austerity measures." The shooting was just the match to start the fire.

Anyway, call the army in and restore order. I remember the riots in Detroit. 43 dead in days ... The state National Guard (para-military) could not contain it, they needed the US Army and tanks in the streets.

Riots can get real nasty and the damage in their wake creates parking lots. The Watts riots in Los Angeles wiped out blocks in 1964 ? when I was there in 1975 they were still parking lots.
