Yeah. Hope this one does not go astray. The thought of banning vehicles makes about as much sense as banning guns. That being said, making it difficult for vehicles to get too close to high value targets--just in case they happen to be filled with explosives--is a reasonable idea. Think Oklahoma City, or the American embassies in Kenya and Tanzania that were taken out by near-simultaneous Al Qaeda truck bombs back in 1998. Or, for that matter, the Marine barracks in Lebanon, or the US embassy in Beirut--the latter having been hit twice.
Hoping that all those currently in hospital make a full recovery. And let us continue to stand in solidarity with our British allies in the war on terror.
