I can see some real problems with this policy in the near future.
From The Evening Standard:
Muslim PC wins right not to protect Israeli Embassy
A Muslim police officer has been excused from guarding London’s Israeli Embassy after he objected to the duty on ‘moral grounds’.
PC Alexander Omar Basha - a member of the Metropolitan Police’s Diplomatic Protection Group - refused to be posted there because he objected to Israeli bombings in Lebanon and the resulting civilian casualties of fellow Muslims.
In a move which has caused widespread astonishment at Scotland Yard, senior officers in the DPG agreed that that PC Basha should be given an alternative posting.
The officer, who carries a gun, is now thought to be guarding another embassy.[/quote]
