Maybe it's time for a few internment camps for all those people who the police and authorities say are 'on our radar'. Why are they walking the streets , with the ability to do what they did in Manchester? If they are foreign and 'on the radar' then deport them. If they are British and 'on the radar' then intern them.

incidentally....I see that Calais is becoming a very dangerous place again, in spite of the camp being razed to the ground a while ago. Lorries and tourists are once again having to run the gauntlet of those trying to get here illegally.
