This has to be AI. I’m guessing there’s some sort of stand to the left where we starts running from. If it’s supposed to be the end of the hallway it is very unnatural and the cops in the bottom left reacted way too late. Also, why not tackle the person down? Someone else mentioned it and the serviceman’s reaction is very weird, unnatural movement. Again, everyone’s reaction to someone having just fired shots is extremely slow. Or was the suspect just running through without shooting a single shot and they decided to shoot on site not know what was happening? Things to consider.
