Or was it? There is good indication that he was attacked a block previously by Antifa folks as he was leaving the car park. So did he really have safe egress behind him or not? I have seen frames from video of cars and people being attacked at the exit of the car park. I am inclined to believe that he may very well have not felt there was a way to just reverse and get away. Take a look at the videos and frames of the car park exit. Would you have gone back there if you knew that was what lay behind you?
Where? And how is a situation you have left relevant to a new and seperate situation? Especially when you're on a street that is empty behind you.
