The terrorist attacks in London and Glasgow

I am afraid that making fun of the terrorists who tried to attack us recently has become common, take a look at this, this and also listen to the jokes on Radio 4's News Quiz and BBC 2's Mock the Week. However the fact that these terrorists fortunately failed in their attacks in London and Glasgow recently just isn't the answer. If the security services are right and there are 4,000 active plotters in the UK then one group will succeed and the results may be even more unpleasant than on 07.07.2005 or even 09.11.2001. I know laughing in the face of such a threat seems the clever and politically correct thing to do BUT I doubt if the same people will be laughing when we are mourning the dead.
