Children have few boundaries regardless of parenting now a days & we don't know where these children are from or their family backgrounds.
A child can call a teacher a cunt and nothing will of any consequence will happen, a few years ago, that would have meant the cane or the slipper.
Its all very well blaming parents etc but the message we keep giving children is they can do whatever they like.
We keep blaming the parents, how about blaming these children? and stop with this "oh poor child" crap.
There is no respect anymore for authority, law an order or the elderly and that comes from society.
In the 70s, my brother was caught carrying a knife as a 14yo, the man who caught him, then twisted his arm so violently behind his back, he ended up with pulled muscles, this man then told him why he should never have a knife and threw it in the river, my DB never carried a knife again.
What would have happened to this man if he did that to a 14yo today? it would be "poor child" and "violent child abuser"
