Dan Bilzerian was there and a girl next to him was shot in the head so he ran to his truck to get a rifle (he usually has 100k worth of the best gear money can buy in his vehicle and far better than anything the SWAT team has). I think at that point the police told him to leave.
That’s a tricky situation. These days, I would have been reluctant to take a rifle out without permission of the police once they arrived in large numbers. It would have been a good idea for them to accept help in the first ten minutes, while the shooting was in progress, but I’m not willing to shoot over their objections or even without their tacit approval. I also do not carry an firearms except when traveling to or from the range or gun shop, not in the People’s Republic of Maryland.

He is an enormous doosh.
