As I was walking to my car, i was called from behind by someone i know and i turned around to wait for him to come and as he got closer he swung a closed fist. I ducked to dodge it and turn around and he proceeded to pursue me and soon gave up the chase. It all happened in a parking lot and im sure 1 of the cameras caught what happened. It happened around 11am on the date of 10/9/13. I didnt call the cops, is it too late to do something about this?
