Very clever. Soaking and humiliating old ladies makes our country safer, PB?
If it stops a breach of security then YES.
They are not all little old ladies either, remember Greenham Common?
As far as the UK or Australia being threatened by drones, I would like to think that the respective air defences will have taken care of the drones long before they are in a position to fire - as an airborne weapons system they are unlikely to be very effective against a sophisticated enemy.
