First Fishie,
I am appalled that you would paste that filth in this pristine forum, the ORG. Fer shame, fer shaaame!

Second,
The riots are most similar to the Detroit riots in 1967. Discrimination was the spark, but disenfranchised youth was the gas, while class, and race separation was pretty much ready to burn. I'm saying regardless of guns, or the lack there of, regardless of immigration, and religion. Detroit fell and never recovered, because the resources to help, and support communities was availed only to those who already had far more than those in the poor parts of the city. The have's nearly ignored the havenot's. Race, and economics became realities too uncomfortable to address. Ask any Detroiter who was there, and they will tell you, that those communities were often well aware it was coming, and still the city leaders just claimed it would be unfair, and unappreciated, to focus it's attention to any large degree on the poorest, and [least savory] segments of the population, insisting the contributing majority wouldn't have it's tax moneys spent more for the lowly, and less for themselves.
Then it exploded, and the fear of the streets long term unrest drove most of the upper, and middle class families out to suburbs, and rural areas. What was left was mostly only the poor, addicts, sickos, crazies, and middle, and lower middle-class black families. White folks didn't feel adequately safe in a place where black people were very numerous, and suburban areas didn't sell, or rent to very many non-christian, non-whites, and some old realtors won't publicly admit it to this day.
[legal posturing]
A city can not [only] support those with good work ethics, and socially comfortable backgrounds. And likewise Motown still can't support it's self after it lost around half of the tax paying, strong property value focused homeowner families. To this day, a live-in homeowner in the city is a very small exception to the renter, and squatter populations. Who cares as much about their community as someone who owns, and is invested in the neighborhood they reside in?
So the only thing I hope for Brits in those places, is that they don't move away, and they know of course, sometimes less is more, and self sacrifice may lead to triumph, or at least something resembling order.
