The media is buzzing; TV schedules all over the place, journalists talking about nothing else, but what actually happened?
Early days of course, but it seems that one man rented a car, drove it along the pavement of Westminster bridge killing people and then jumped out and ran up and stabbed (to death) a police officer.
So one attacker, zero guns, zero explosives; this has to count as a minor effort, possibly even a spur of the moment thing. This is getting off lightly compared to what could have happened. With a modicum of organisation there would have been multiple attackers, they would have crashed PMQs not turned up too late, and been armed with AK-47s. The death toll could have been substantial. We should be grateful muslim terrorists are mainly useless.
