I felt sad and shocked to hear about the political assassination of Pakistan's Benazir Bhutto today.

You can't get rid of opposition by squashing it or killing it. The more force is used to suppress people, the more the potential for the eventual backlash will grow.

This will have big implications for our world.

Personally, I had an odd connection with Benazir. She was kept under house arrest for a large part of my primary schooling in the house across the road from our school in Karachi. I was scared of the bayonet-toting guards who patrolled her fence line and often thought about her not being able to go out and be free.
