that was just agent vs agent....intelligence agency vs intelligence agency...not car accident or anything...
maybe the pakistani motorbikers were not directly hired by ISI, they could be assets or what ever...unofficial operaters...basically just hired thugs, same as raymond davis, former soldier working as a spy for CIA...
what's unfortunate was the death of the third guy who had nothing to do with this (got hit by another car coming to help raymond davis)......
