London bombing

There is a bunch of plain clothes police officers who periodically roar off past my house in flash–looking unmarked Audis, BMWs etc. Seeing a bit more of these guys lately. Saw them deploying in numbers on Friday morning and again on Saturday afternoon. Although on Saturday, one of the vehicles in the luxury car convoy was a rather incongruous old Sherpa van with a ladder on the top. I suspect that these guys must be engaged in the search for the 21 July bombers. I suspect that the police are all pretty busy at the moment.
