You said that "It fell because a fifty pound child was repeatedly yanking it down onto himself for the better part of a minute."

The video at the newser.com link in the OP shows the boy running to the sculpture, stopping in front of it at the the two-second mark, starting to climb it at the three-second mark, and the top piece of the sculpture hitting the floor at the thirteen-second mark.

So about 10 seconds from moment he first touched it, which is not remotely close to "the better part of a minute."

I didn't see the "repeatedly yanking it down" part you mentioned, either. I saw him put his hands on it, and then spend a good 4 or 5 seconds of those ten trying to keep it from falling after it started tipping forward.

Is there a different video with a different timeline and different actions than the one shown?

If not, I'd have to say that an unsecured $132,000 art piece capable of being toppled in 10 seconds by a five-year-old shouldn't have been placed in a community center whose website proclaims:

"From toddlers to seniors, TRCC offers a fun and active environment that everyone in your family can enjoy."

A facility that markets itself to families with toddlers has no business putting extremely expensive, fragile, and dangerous items in the common areas of that fun and active family environment that they advertise. That's just common sense.
