Excellent.
At 32 seconds in the video you see him (Good guy-GG) rolling his chair out and at 33 you can see his gun is already drawn
At 34-35 seconds he is rapidly approaching the Bad Guy (BG1) initial from behind, BG1 spins and sees him coming with drawn gun and BG1 starts moving and a shot is fired.
At 36 seconds BG1 is sprinting and lady by stander is now covering ears (obviously 1st shot has already taken place)
At 37-38 seconds you see him take another shot at BG1 (now off camera) or possibly BG2 standing in the corner
At 39-40 a new angle as BG1 is falling (shot in hip/leg?) Notice our GG had clear field of fire...no one behind BG1 or BG2 at this point. BG2 is in corner and follows BG1.
At 42 you see GG coming into camera view following BGs with gun at ready
At 43 you see him take a shot with a second at 44.
Camera angle swithes and you see these last two shots again in the door way.
Way to go good guy!
Looking very closely, I believe the shooter had to rack the pistol and chambered a round just prior to firing.
In other words, his gun did not appear to be locked and loaded.
No fanny pack, shirt tucked in wearing shorts. Appears he had the pistol in his pocket. Just guessing.
Great Zagruder-type analysis of the video. I appreciate it.
