I watched a cab drivers video, you can hear 3 different areas where shots are coming from, and several videos showing some shots coming from a much lower floor.\nI also used to watch the series Vegas about the security in the Mandalay Bay.\nUnless someone leaks the truth with MORE evidence - it's JFK all over. We have more technology these days and camera everywhere including peoples cell videos they were taking during the concert. Jason Aldean was singing - the cell phones were recording.\nNo one will know who.\nBut we all know why - to take the guns and write more laws \nEvery week someone is running a vehicle through a crowd - they will eventually put a computer chip in our vehicles that allows the cops to stop it in its tracks. Until some hacker psych starts turning off all our cars, we will think it was a good thing because it prevents these atrocities.\nI fear for the future of our kids.
