Are refugees welcome to plant bombs on our trains?

It’s all a long time ago now isn’t it? All of three days since someone put a bomb on a London Underground train and then stepped out of the carriage. Thankfully the detonator went off without managing to trigger the main bomb, which isn’t a mistake we can hope for every time. 30 people were injured on the District Line on Friday morning. But if the bomb had done what it was meant to do then those 30 people wouldn’t have been treated for relatively light injuries. Instead, bits of their remains would have been gathered together in some order and put into the dozens of body bags ordered for them and others at Parsons Green station.

It remains strange how fast we pass over all of this.
