Graham, I'm sure your father was one of the good guys in government, but I'm also pretty sure that if this was a forum about the Iraq war or some other such, you wouldn't have any problem with someone criticizing the integrity of government.

I'm a professional historian and I've spent my life studying a hell of a lot more incidents of government malfeasance than just the nuclear industry. You're right--there are bad people in every profession. However, when they crop up in government, their reach and effect have much longer legs. Moreover, government is a public service, and public services are therefore subject to oversight and criticism.
