Note that the Metropolitan Police cannot use tear gas to deal to these thugs, it cannot even contemplate rubber bullets, because you see to protect people with more force would be against the rights of the criminals. Neither could those whose businesses and homes were attacked could ever have a firearm to respond.
However, just wait to see who politically around the word spreads the empty nonsense that the riots are about the death of Mark Duggan (who did not exactly appear to be unfamiliar with the gang culture that infests Tottenham), or about the cruel Tory government that has cut government spending to a heartless 51% of GDP, or that its about racism (given the majority of rioters have appeared to be Afro-Caribbean), and how the way to fix it is to borrow more money we don't have to spend money on more regeneration, state housing ghettos, welfare and pseudo "jobs" with local authorities.
Whilst, of course, the people whose businesses are wrecked, who are unemployed as a result of their employers' businesses being wrecked, who are now without homes, are ignored - for they are the "collateral damage" of "disenchantment", rather than a victim of decades of failed welfarism and state housing ghettoisation, producing hot houses of feckless dependency and criminal cultures of violence, misogyny, gangster worship and aspiration less traps for the children raised in that culture.
UPDATE: Oh and remember more than a few of the parents and relatives of these thugs DO want better. Read Katherine Birbalsingh's column about how SHE talked to an event about young black men in London, she's an inner city teacher, who has riled more than a few because she spoke at a Conservative Party conference.
