Will They (We!!) Ever Learn

I'm in London. British Foreign Secretary Jack Straw in deep doo-doo. He shook hands in public with bloody dictator Robert Mugabe of Zimbabwe. Caught out, he complained that, well, the light had been bad. (All press pics as clear as a bell.) Is the lesson, "Don't shake hands with wretches?" No! No! And NO!! The lesson ... THE LESSON ... is don't be a total jerk and engage in a clumsy cover-up.
