As for Coulter, that is just a lazy article.
The Shannon Matthews case was - which for some reason Coulter fails to mention - basically a massive attempted scam perpetrated by the mother and the "step-uncle" (who was actually the mother's boyfriend's uncle), with the aim of conning the media into paying for exclusives, and of getting their hands on the reward money that had been offered. A good part of that community spent ages searching the area for Shannon, in the way that communities usually do when a child goes missing - you cannot judge an entire people by the actions of one especially vile criminal (Shannon's mother drugged and tied up her own daughter for nearly a month in an attempt to get the scam to work).
She has missed considerable bits out of the Scarlett Keeling case as well - not the least of which is the fact that it was only the mother's fight to prove that her daughter had been murdered (Indian police insisted that she had drowned until a second post-mortem showed she had been drugged and raped) that led to any kind of justice at all.
The rest of it is just lazy stereotypes that some of you lot fall into using every now and then. Riots after sports games happen in most countries, including your own. "Kaffir" is South African, not British. The authorities are that weak and so ineffectual that people are being handed six month prison sentences - after pleading guilty - for stealing £3.50 worth of water, or looting a slightly more valuable cake. As the result of these riots than 1800 people have been arrested, 1300 charged and the majority of them imprisoned at once (either on remand or after pleading guilty).
Most importantly, she has neglected to mention the fact that members of nearly every community - indigenous British, Muslim, Sikh, Turkish and the rest - that was affected by this came out onto the streets to protect their communities against further looting, and have been helping to clean up and to raise money for those people who lost their businesses and jobs. This was unprompted by the state, uncalled for by politicians and is exactly what the generation of 1939 would have done (and of course, did).
