I take it nobody has heard of the McPherson inquiry...
To be honest, it sounds from ruby's story like the police were just trying to look like they were doing something. Though to be fair, I don't know the details. But that's how it sounds, and it's certainly not an infrequent attitude.
am fed up with certain sections of the communities expecting themselves to be free from police attention just because of their race, religion or whatever.
It's nothing to do with race. They merely expect to be treated as citizens of the UK (which they are) rather than potential terrorists. Quite reasonable, really...
did they hand over those that were preaching anti westeners, anti Jewish rhetoric in British Mosques?
Did they need to? In most cases, the police are well aware of such people.
And even if that wasn't the case, perhaps they'd feel more co-operative if they weren't being constantly profiled due to their ethnicity.
