For such an event, you really want to know there has been a proper investigation.

I dont know if there was a video, what it showed, how many people died, how many were combatants, what their ages were.

If I was a soldier.. Id want to know that these things are investigated well.. because I really don't want to kill innocent people by mistake. Where did the mistake happen along the chain of intel and of command, who didn't double check, was someone gung-ho or negligent ?
