[null and void]

I think you overstate things by saying he was seen coming out of a 'terrorist safe house'. He came out of a block of flats that contained an appartment that was under suspicion.

Perhaps I am. That is a detail I wasn't aware of. Is it true? Source please?

Source was Metropolitan Police commissioner Ian Blair on Sky News this morning. He initially said 'house' in reference to the building, but then clarified that the building under surveillance was a block of flats. He was questioned as to how many individual residences that comprised, but was unable to give an answer to that.
