This is all imho a direct result of what my owner likes to call....The pussyification factor.
Back in the day the teacher would have been able to most likely easily taken the child in hand and delivered a few well deserved swats to the childs fanny to chastize him and that would have been it, end of story. Of course back in the day the parents would have raised the child to respect authority to begin with too.
But in today politically correct world, the teacher doesnt dare touch him for fear of a lawsuit and all sorts of cover one's ass procedural bull crap has to be resorted too, and sadely enough, the parents probabely dont spank him eaither for the same fear that they will get prosecuted.
I bet whats made out to be so shooking in the report is actual "procedure" and school doctrine being applied as it was desgined by lawyers to avoid lawsuits from angry parents who would sue the teacher if she had intervened personally and disiplined the child.
Of course the story is coming from a onesided source with an agenda, so I have to take it with a grain of salt, it looks like there is a wholle lot more going on than what was reported selectivly in the article.
The hospital trip also sounds procedural, and more "cover one's ass" pc bull crappy at work.
