I just watched the new video on MSNBC and Its sickening to be honest. I had friends sitting at the far end of that box and I was supposed to be there with them. They were okay but Said that the scene was awful. I am glad I was not there in person to witness it.
While the deaths were bad enough, many of the injuries were pretty horrendous from what I've heard from Fire/EMS workers present and from photos. An instant Mass Casualty event if there ever was one, akin to a bombing.
