It can be useful for people to see how other countries handle crimes like this one.
I’m from the US and if this happened here depending on what state he was in would determine whether he got a slap on the wrist or jail time. Also if the judge was corrupt or a shitty person he’d get a slap on the wrist(see rapist Brock Turners case).
So it not completely useless. At least I don’t think so.
