Bronze is pretty soft stuff, and as the post mentions banjos are pretty beastly. Plus I seem to remember this thing requiring repair/restoration before thanks to weathering or damage.
Those make a little more sense given how sentences work here, where you often don’t serve the whole thing and there are multiple ways to get out early. You start looking at major crimes of the past, serial killers and what have. And you see a surprising amount of people getting sentenced to effectively the rest of their life for the sort of shit you seriously don’t want wandering around the street. And yet they get released in like 7 years.
So the idea is to stack up multiple sentences, and force them to run consecutively. So that even if some one serves the absolute minimum on each it still keeps them locked away forever. It would make more sense to update our whole approach, and most of the time there’s really no call or point to applying that. But there is a reason for it beyond an impressive headline.
