The above incident is a first, but by no means uncommon. Countless cases of "happy slapping" are going on in schools, dark staircases, during eca initiations, birthdays etc. Basically anytime and anyplace is good for them to kick/slap/strip/humiliate someone(usually weaker and outnumbered) and record it, then post it online for all to share.
I shudder to think what the future holds if these are the warped values that our young people have now. Many have came together to discuss how best to curb these adolescent gangsters( cuz that's what they are behaving like). Most are taking a softer, benevolent hand, often sending them for counseling or back to the parents.
Me? I'm old skool. I say hit them where it hurts; their young ego. Send them straight to boys/girls homes. Get them to wake up early morning everyday and do drills, have them pick up litter on the streets, parade them in front of the whole school, put up their photos in the papers. I've had enough of them being counseled, given countless chances to turn over a new leaf, and still not learn anything from it all.
It's time to return the power back to the adults in their lives.
