Just watched this for the first time today. It was really well done (except for maybe the ending of it, toward the credits), but I don't think it went quite deep enough. At best, multiple agencies, media and police were insanely incompetent throughout the whole ordeal, and at worst, it's all a ploy to push gun control.

I think time will tell. The kids that were involved with this stuff will come forward as they get older, and their story will be told. Maybe not in full, but it'll get leaked out eventually.
