As bin Laden was holed up 800 yards from the Pakistan Military Academy, it seems more likely that he was captured by ISI and/or the Pakistani army, as opposed to trying to hide from them there.
ISI dealt with bin Laden in the 1980s, and has good intelligence in the region bin Laden had been rumored to be holed up in.
It takes more of a leap of faith to believe bin Laden was hiding from the Pakistan military/industrial apparatus 800 yards from the Pakistan Military Academy, than that some high officials knew he was there.
