It's an obvious deficit in civilization itself that we can't have, or even seem to come up with, a principled justice system. We just intermittently ban specific atrocities and hope that eventually adds up to justice.
But too often the system makes criminals into worse humans. That’s unhelpful.
Being laxist towards criminals is not just being cruel to the victims to me: to me it is downright complicity with the criminals.
BTW: Japan happens to be one of the safest country on earth. A friend who's a pilot told me: "Tokyo is the only city in the world where I've women from my team (mostly air hostesses but also female pilot or co-pilot) go for a run at 3am". Now he didn't fly to every city in the world but I can name a great many cities where a fit woman won't go joking in yoga pants at 3am. And so can he.
Japan is safe because of other factors, not their conviction rate.
> they swipe up every single criminal they can, plus a bunch of random people
And this is completely baseless.
There are many places women can run at 3am - Singapore, Bangkok, jut from top of my head.
And living in Tokyo, I woudn't advise any women to do jogging at 3am.
