Not to defend the operator with the lead foot but those shelves appear to be extremely overloaded. They look like shelves designed to carry pallets of stuffed animals, not liquor, or any other liquid. Damn shameful waste of some good booze.
Although I bet a good majority of those bottles are still intact.
They showed a video that happened at our work a couple years back that ended the same way.
They guy was driving and just clipped an keg end of the shelf and the whole thing came tumbling down. S*it would be scary if you were in the forklift driver's shoes.
