To be honest anywhere there is a collection of people is a target be it an airport,rail
terminal, shop,concert, bus stop or busy street. The government put the restriction on
airport terminals after the Glasgow incident because it could cause massive damage
and huge delays let alone all the people that would be there which doesn`t bare thinking about. I was at the Manchester arena a few weeks ago and the delays to get in were substantial along with several checks incl airport style body checks which I have got to say was fine by me.
