Bhutto assassination

A few questions and observations:

Bhutto was shot in the same park where Pakistan’s first prime minister, Nawabzda Liaquat, was assassinated in October 1951. Was that intended to serve as a message, or was this just the most convenient place to strike?

The assassin shot her, and then blew himself up. Is that a normal pattern for Rawalpindi (a city with over 50 suicide bombers last year, as I recall)? If he had already succeeded, why would he blow himself up? Just to avoid questioning? It doesn't feel right.

Let me get this straight: a dangerous city, an obvious target, and a lone assassin who dies before he can reveal anything of interest. The conspiracy theorists--and Pakistan is loaded with conspiracy theorists--are going to have a field day.

No conclusions. Just thinking out loud.
