@layman,
To be fair this seems to be the attitude of most Londoners.
Having gone through the bombings of Nazis and the IRA they have developed a very fatalistic attitude.
I can assure you that they are going to resist any notion that they need to change their daily behaviors, and there is courage behind this, but they don't need to change their daily behaviors (gathering in large vulnerable crowds outside pubs after work) to combat the threat that is growing day by day. They need to change any notion they have about the power of
love and
tolerance.
They really aren't willing to die for the sake of John Lennon's notion of
love, but when the threat is so dissipated among millions of people, it's easy to take a detached view.
