You will never find me complaining that security measures should be tighter. If we want to avoid any more bombs going off in the UK or US we should stop setting our own off in other countries.
Not that any of this has anything to do with preventing bombs or terr'ists - it's just the usual combination of intimidation, deception and abuse designed to gradually wean us off those troublesome ideas of freedom, self-determination and independence so that we all cower in fear of the evil monster and get on with our daily responsibilities of working our lives away for the benefit of our masters.
It's awful when people are blown up - at home AND abroad. Apologists for the system which allows this to continue share responsibility. That means you.
