10 years of a person's life for a (really stupid) childish mistake? And of course when they get out of prison there will be serious career impact that will last their entire lives. What they did is horrifying, but barbarism can't be the right answer.
Bypassing security of the type described and being oblivious to why the security is there requires a type of autonomy and narcissism that exceeds "childish mistake".
Everyone is tough on crime when they are personally offended.
Eh, maybe that's taking it all a little too seriously. For all we know, the original art was the work of some ancient hooligans.
We don’t have very much evidence of ancient human art work around the world. Each one of them is precious.
To make it morally equivalent to graffiti is ridiculous.
is it more precious than one human life ?
It’s definitely more precious than the life of a scumbag that spent considerable effort getting through security measures just to destroy this thing.
Thank goodness you're not in charge of the justice system.
Right, it's not like there are living stewards of the art who could've told you what it meant!
Oh wait...
Draconian punishments aren't a good way to protect ancient relics. It only takes one person to not even know what the site is, let alone the punishment, to ruin it forever. Also, it's cruel read-a-news-story desire for vengeance for damaging something you probably never even knew existed in the first place.
