Sandy,
You are absolutely right.
Considering the current circumstances, a man who is challenged on the Tube and then persists in running away from armed police, should be allowed to amble nonchantly down to a packed tube waiting to depart. Far better that he then explodes a bomb and kills 30 people, than the police bother to intervene.
Sandy...you forget to understand the seriousness of this man actions against the current climate in the UK.
For those of you too stupid to realise, we are now at war in our backyard with terrorist extremists.
This isn't the sort of "one bomb a year" threat from the IRA which most of us lived with in the 1980's-1990's..this goes much deeper than that.
This is all out war Sandy...the extremists will stop at nothing to destroy our way of life.
There is no room for stupidity (witness the man shot dead).
There is no room for indesision.
There is no room for perhaps, what if, or suppose so's.
It's kill or be killed. Like it or not. The time for liberalism is over.
Welcome to the UK.
