UK has it tough police wise, this is an age where we get told by the council to "Remove your St. George's flag from your window, because it's offensive to minorities".
Police in the UK treat everything with kid-gloves now. Not their fault, they "have" to. Political correctness (Tamals in London atm, police won't touch em, lord knows it'll be "racist"), and modern media* means they're extremely limited in their choices of action.
I really feel for the average bobby atm, in many respects, they're powerless. Bring back the days when a delinquent youth yelling abuse at a police officer, who then goes on to steal 3 people's phones at knife point would get a slapping. Saw a two PC's (one white, one asian, both female) taking an untold amount of verbal abuse from 4-5 male black youths, who practically followed em down the street continuing the abuse(reason PC's did nothing? probably scared of being called a racist), this was about a year ago, it has only gotten worse.
Bottom line, give UK police more rights to uphold peace, without fear of persecution for doing so.
*Camera phones, personal camcorders etc. wielded by the public can be used against the police, when shown out of context. e.g protester spits in PC's face, PC gives him a beating to the legs with truncheon, filming of beating, then distributed to the news desks, PC gets persecuted, and dismissed from police force, despite him being in the right.
