Does the 'shoot in the head' policy only apply to our chums of somewhat arab extraction or can they now shoot Mr or Mrs 'white middle class' as well?
I am sure that if Mr or Mrs 'white middle class' were under suspission of a possible suicide bomb attack, ran away from the police and acted in a manner that could be construed as threatening the lives of the public, then yes, I am sure they would be dealt with in exactly the same way.
However, the threat is currently from the Islamic extreemists and they, on the whole, are "our chums of somewhat arab extraction" as you so elloquently put it. It is no wonder that people are more suspicious of Asians carrying rucksacks on public transport than Mr or Mrs 'white middle class'. It is not racist, just natural fear and suspision.
