Off the graph.....

After the atrocious, psychopathic attack on what Isis call the 'Crusaders in their Shameful arena' (ie teenage girls, mostly, at a concert, in this case). It looks like the 'threat level' has shot up. (Perhaps the detection level has shot down).

I noted on Radio 4 that the Home Secretary was asked if putting troops on the streets could be seen as 'opportunism'.

Not a chance.
As if they'd be as cynical as that.
