A large backhoe was scraping down the exterior walls of a building on the corner of a busy intersection. The road wasn't closed, nor were the sidewalks next to the construction site blocked.

Why these preventative measures might have been advisable makes itself apparent one minute into a video that shows how not to demolish a building.

Perhaps the sign mounted on the crumbling wall said something to the effect of "hard hat required," but we can't tell. And, to be fair, it appears as if the sidewalk at least was covered overhead.

But it wasn't enough. After one wall toppled, another followed in a domino effect. Bricks and other debris littered the street, but it didn't look like anyone was hurt in the incident.
