Sometimes, troubled kids need the !@#$ scared out of them. Does is work every time? No. But coddling kids doesn't work either and if one kid convinces the others that there is no authority, then anarchy rules.
BTW, back in my day, the parents usually sided with the teachers and staff. Because it was clearly understood that parents can very easily undermine the schools authority and that hurts the child. Ya, know the unified front. BTW, this works with parents too — if the mother and father cannot agree, then the kid wins. Another cliché — divide and conquer... and kids figure this out at an early age.
Thirdly, societies standards have dropped considerably. Back in the day, adult peer pressure and public scorn helped keep people in line. Thus the reason why the case needs to be publicized. Now, it is pretty much anything goes and it is far from conservative... anything goes is usually a Liberal mantra.
Lastly, for a kid to be taken in handcuffs, he must have done something really bad and that usually means a threat of violence or actual physical violence towards a teacher or the office staff.
I was agreeing until you got to the “Lastly, for a kid to be taken in handcuffs, he must have done something really bad...”
You are assuming a basic level of competence and honesty in the principal or police that is patently absent in our society. This is a huge blind spot in traditional conservatism—you expect government agents to act within reason and law.
In our case, that hasn’t been the rule for 40+ years, and the trend is not your friend. Totalitarianism always starts with a call for law and order—and ends with death and destruction.
