Probably the only thing anyone can say about this latest atrocity is to 'stay calm and carry on'. Terrorist organizations thrive on the over-reaction from politicians and police who understandably want to protect their people from violence but end up, as the author suggests, doing things that act as recruiting tools for more extremism. Extremism can be defeated but only in the long term and after many more deaths. It's vital to maintain the dignity of our civilization and not stoop to the level of the terrorists.
