Police cordons

Something we've gotten used to in the UK through the years of the IRA threats, is police cordoning off chunks of London, typically a few blocks as a result of having a suspicious package or car.

Today was no different, with people calmly walking away from the cordoned area as directed by police on site. It's markedly different from the general panic typically seen elsewhere around the world.

I wish this calm attitude was something intrinsic with people, rather than having come from repeated exposure to such threats.
