I’m getting old! I watch that video and think, “who let that kid play around on that statue?” and apparently he’s old enough to be criminally responsible haha.
I agree with that, but a culture needs to own its heritage, both the good and the bad. From what I can tell, that hasn't happened compared, for example, to how German society has handled the Holocaust (an extreme example, but illustrates a point).
People are going to climb statues. The owners should have made sure it was durable enough to be left in an accessible location. The kid did nothing wrong.
liability insurance. In Germany, there are many that contractually agree to not refuse payment when the liablity occured out of gross negligence, which this would be by German standards... Yet... you were aware that this was a somewhat sarcastic remark and not me actually giving insurance advice, right?
Since this was clearly negligence, I think they would be fine. After all, they didn't intend to damage the statue. Gross negligence is still negligence.
