But yet you took the picture anyways.

Flash damage?

Pictures, just like food, get a lot more interesting when there’s just a little bit of crime involved

I’m just guessing, but maybe it was selfie/portrait accidents in the past, where people came to close to the exhibits, toppling them over.

After taking a better look: everything seems firmly secured here. I still think preventing portraits is a possible explanation: No accidental touching of the objects when people hold their face too close, or grabbing of objects when they stumble during posing.

I’d assume to try to curb duplicates/copies from being made

That place is great! Much better than what they used to have back in the day. I was rather impressed when I visited a few years ago not knowing this had been built since my last visit.
