I am just watching this video now, when he is fiddling with the camera there is an explosion... he casually takes 20 steps to see what happened... thinks to himself he needs his plate carrier (probably department policy and not "o shit were in a warzone better get ready... because If that were his thought, he would have also went for his long gun I am sure is in the car. and btw he is ~100 feet away from where debris fell and his breathing didn't change...

not even from the shockwave and the rush of adrenaline... not only do you know there is a bomb and where to be no where near it you have to know about it for a long time before and even then.... maybe only warzone operators would have enough ice their veins to stay that focused.

Edit, I looked back and it didn't appear to me or I cant tell if he had a soft vest underneath his uni, so getting a vest makes sense, however the point still stands... I wonder what their policy is because I can't remember the last time I saw a duty officer not wearing a vest in my state,
