Did American Soldiers Delete Footage of Alleged Bloody Attack on Afghans?

We know something pretty horrific happened in Afghanistan that day and that at least one American GI, along with others, have said U.S. troops just opened up fire on anyone and everyone around in a "blind rage", killing women, children, and old men along with others. If it's true now that soldiers deleted photos of the carnage, it may tell us a LOT of how horrific their acts were. From the BBC:

The Associated Press is to complain to the US military after journalists said US soldiers deleted footage of the aftermath of an attack in Afghanistan.

President Hamid Karzai said 10 people died when coalition forces opened fire on civilians after a suicide attack in eastern Nangarhar province on Sunday.

Journalists working for AP said US troops erased images of a vehicle in which three people had been shot dead.

The US military said it could not confirm its troops had seized any film.
