Since Musharraf helicoptered in (in 1999 he ordered the ousting of Nawaz Sharif from the safety of his airborne 'copter) he has been following the IMF recipe for success: all those well known austerity measures and opening up the country to the highest bidder stuff. Which is to say, the entire nation's piss-poor infrastructure is slowly becoming foreign (private hands) owned. The results, as always (cf; Argentina) means the creation of a new 'middle class' who suddenly own shares, has not just one, but two cars (many run on natural gas canisters) goes shopping to the new mall, has offices in the latest foreign funded construction on the edge of the city and sips coffee in pseudo-Starbucks smoking Marlborough.
The famed economic miracle of Pakistan has totally passed over the heads of the people mentioned in the article The Dude posted, who suddenly find they can't afford basic produce. The reaction to Bhutto's assassination was not a nationwide outpouring of grief over the loss of another Dear Leader, but mostly the opportunistic looting carried out by this perpetually downtrodden underclass. The one Bhutto is supposed to have had her grass roots in. She did not even speak their language, English was her first language, she was taught Urdu which she spoke grammatically incorrectly, and her Sindi (her own constituency/province) was practically non existent.
Rioters and looters were ripping out the whole ATM, not just holding people up in their cars and stealing watches. This is not 'politically' motivated, unless you want to claim the looting in New Orleans was also politically motivated (arguably, that IS the bottom line.)
The difficulty for Western on-lookers is the ghastly contrast between those rubbish strewn streets, where dead chickens and offal are simply discarded in the front gutter, and our manicured lawns and garbage collection ... People in Pakistan have had meat rationing for years. When you do find running water (in the major cities and upper crust hotels,) it is guarranteed to poison you. During the annual Shi'ia celebrations of Muharram, people get killed. During the yearly kite running Springfestival, children die decapitated by the unseen glass coated wires strung across the road, as their fathers drive them home on the back of the motorbike. And the kite flying and the wires are both officially banned .... I've seen pedestrians knocked down and immobilised in the busy main street of Lahore, and the driver simply speed off. The newspapers report these kinds of small tragedies, daily. If you haven't been there and witnessed it, if you haven't seen and talked with the people, all you can go by is what you're told by the Western media, and whatever spin they want to put on it.
All I'm saying is, a lot of the rioting and looting is, as Pana Burda says, normal. Not immediately to do with the political or energy situation. It's just the usual victims taking advantage of a power vaccuum and the opportunity to grab what they've been denied and also lash out at their masters. It has always been like this, and likely, always will be.
As far as conspiracy theories go, I read on another forum that Arlen Specter (?) apparently the one responsible for the official JFK story was actually in Pakistan the day before the government released the official story of Bhutto's unlikely death from a bump on the head while ducking the assassin's bullet. The truth is being spun and spun, to end up with a similar 'magical bullet' or 'grassy knoll' confusion which hides the kernel of truth, making it indistiguishable from the inventions.
Anyway, this is the best assessment I've seen so far in the Western press:
