It all looks like a botched attack or some dubious attempt at a hoax (which is still a serious crime), even though there do not seem to be any physical injuries - plenty of people will be suffering from shock and psychological injuries.
Compared with two weeks ago, the official infomation being given to the public by the authorities is no better.
The use police sniiffer dogs who are checking the evacuated passengers at Warren Street is noticable, something which was not in evidence two weeks ago. Presumably because of the lack of physical injuries, some of the passengers and staff are being questioned on the spot.
The ever increasing size of the cordoned off areas also seems to be an unecessary disruption to traffic. This implies a lack of information or overreaction by officers on the scene.
Why is a 400 metre cordon needed around a deep underground station like Warren Street ? Why is the whole of Shepherds Bush Green , amjor road junction now sealed off ? Why is "half a mile" of the Clapham Road by the Oval sealed off ?
This is the wrong kind of risk assessment - if there had been real bombs, extending the cordons bit by bit, every 20 minutes or so is insane.
