All very possible. There are just not enough angles and details at this point. However, I do know from years of executive protection training that we are trained to shield the mark and remove them from the scene as quickly as possible. You do not allow the mark to say, hold on, let me get my shoes, then fist pump and pose for photos before doing this. The reason for this is that there could be another active shooter. This is basic stuff. Get the mark to safety. Do not allow them to stop for a photo op. Either way, looking forward to more details as they become available.
