not flash bangs. only 7 grams flash powder very little over pressure no need to vent. larger charge from inside the room.
the car arrived and was shown leaving. someone got dropped off at the front door. important people dont drive themselves
person leaving is not the subject. all shots show the car pulling in, at the building and leaving
bigger then a flash bang
likely not a flash bang to make this mark on the outside of the building. bang just is not making enough total pressure to vent that far outside. likely a much larger charge place ahead of time. not everyone is going to jail.
