There were other people dressed up for the premier. Wouldn’t be surprised if a few were wearing the mask from the bad guy.
Plus like I said what if he had a regularly dressed partner covering his back somewhere in the theater?
So while you duck, he’s just slaughtering lamb. Lot of good you are. Pretty sure it didn’t take long to fire off all those shots, with tear gas in the area especially.
Everybody is a hero on paper in hindsight. It’s different when you’re actually there.
Would not be surprised if there were people there with conceal carry that just ran out in the confusion instead of becoming judge dread and risk being sued for everything they own and ruining their entire life for making a quick split second decision and hitting a wrong guy.
