The UK implemented the same policy within 24 hours based on reliable intel of an imminent threat of that nature. A laptop bomb was used on an African airliner last summer and blew the side out of the cabin.
And in other breaking news, London hosts this week's deadly Islamic terror attack. The new modus operandi being applied; mow down pedestrians in a car, get out and start stabbing everybody. This one on the steps of Parliament, no less. Of course, politically correct media says the attacker was "Asian" in appearance. Witnesses and photos on sight confirm middle aged male of middle Eastern descent with full beard. This attack on the heels of another a few days ago in Germany where a knife wielding suspect attacked on a train platform screaming "Allahu Akbar" (what a surprise?!)
