We could get in a mess with the SAS.

According to the Sun (yes, I know) we can all get stuck into the Xmas shopping safe in the knowledge that the SAS (Who Cares Who Wins) are patrolling shopping centres with a brief to "engage and neutralise" possible terrorists. Let's just hope that we don't end up with SAS troopers clearing a shop full of UK UnCut protesters with stun grenades and Browning "double taps" to the head.
