Michael Hayden

I'm a career Air Force officer. We have a saying in the Air Force: 'If you want people to be with you at the crash, you've got to put them on the manifest.' And so I was always of the view to almost leave no stone unturned when you're up there briefing the Hill.

I told them that free people always had to decide where to draw the line between their liberty and their security. I noted that the attacks would almost certainly push us as a nation more toward security.

As England manager I always felt we needed an extra man in midfield to retain the ball, but that was more as an attacking ploy to help create opportunities. It came from my experience playing international football in a 4-4-2 and spending half my time chasing the ball.

Mostly we're motivated to control ourselves in public. Mostly. At home the motivation is much less clear. At home there's a bit of a lab for bad behavior. You can test things out without terrible consequences. Or maybe the consequences are there, but they are deferred, buried, much harder to detect.
