It might be easy to say "why do the investigation, it won't bring him back", or "I think we can all do without government speculation into friendly fire incidents. I don't care if someone in Iraq died because they tripped on a rock or dove on a grenade to save someones life.", but as a member of the military I hope they get to the bottom of the story. I know friendly fire happens and I accept that, but the only way to reduce the chances of it happening is to investigate EVERY incident and figure out WHY it happened and I hope they aren't just investigating this story because he was a ex football player, every case like this is investigated, the only reason why its going public and getting so much attention is because he's a ex football player.
