>given all the videos online of kids beating up teachers and getting away with it I don't think I heard of a single such story in my life. Is it a thing?
Yes unfortunately. There are TikTok "challenges" go slap your teacher for example. Similar to the "challenges" where you should eat a spoon of cinnamon, eat a Tide pod, etc. There's an air of do this and film it for clout. Most kids roll their eyes as well of course, but there are people who follow along.
These are mostly of the "razor blades / drugs in Halloween candy" sort, where there's a lot of breathless coverage but very little actual evidence of it happening in the real world.
