> Applying violence to kids is not the way to make them stop applying violence to others.
When I was young me and two of my brothers were one-day really misbehaving. My grand-father, who had been capture on the first day of WWII (well on the first day Germany invaded Belgium) and spent 5 years in a PoW prisoner camp in Germany, wasn't a little wuss.
He spanked our three arses so bad I remember it to this day.
It was an amazing lesson.
Something has to be said about peaceful time that create weak men who then find all the excuses towards abusers. The issue with the "well-thinking" mindset is that when pushed to its logical end, rapists are walking totally free after having been caught (UK) and people can break a female police officer' nose at the London Heathrow airport and walk totally free too. With weak judges from a weak society ruling that: "In their culture/countries men don't know that you're not supposed to rape women".
We then end up with people, in the west, who genitally mutilate women and non-sense like that.
When, on the contrary, you decide to take the psychopaths who ruin society for everyone by the scruff of the neck and put them in chain, you get the homicide rate slashed, in ten years by 100.
That's not being decimated: that's being decimated and then being decimated, again.
1/100th.
> So what is the possible solution then? Protect those who are vulnerable
That's typical victimization, which create more weak men. Weak men who then, for example, become politicians who vote ultra-lax laws and weak judges who then let rapists walk free, making the streets unsafe.
If bullies getting spanked by an authority figure don't get the lesson, it's their problem. Not society's problem. Society, as a whole, is supposed to have the monopoly of violence. Instead of that in many countries (like France and the UK), the government gives up and gives the monopoly of violence to drug dealers and rapists. Drug dealers and rapists who learned, since a young age, that were exactly zero repercussion when being a bully.
You've got your opinion, I got mine: putting gang members in chains in El Salvador slashed the homicide rate by 100x. Ponder that.
