It wouldn't look like that and there'd be visible water damage.
The doors were opened with impacts to the handle area. Obviously a battering ram was used, possibly police.
Probably the aftermath of an emergency responders' training exercise. The university I work at had a building slated for demolition and the police and firefighters used the opportunity to train with a more realistic response.
Alternately, it was no training exercise and some real shit went down.
Nah, that feat in the video is a person opening an unlocked door with its crash bar. That is a below average human level feat. It doesn't scale to the wall level feat of damaging a metal door. =p
