Chai and Squinney - I think you guys are right on the money. I'm wondering why at the end of April, there is no behavior plan in place for this little girl, given that it has apparently been a problem all year.
As a teacher who has worked with special needs children for twenty years, I noticed right away that this little girl's verbal development seemed to be very delayed, maybe because she has a receptive language or cognitive or developmental delay. Maybe part of the problem is that she doesn't understand (during the lesson) what the hell she's supposed to be doing, so she just does her own thing, and is viewed as being "disobedient". Then maybe it escalates, because the teacher gets sick and tired of this kid "never listening". Of course, we can't know for sure, but I've seen it so many times, I'd be willing to bet my bottom dollar. Fortunately, it usually doesn't snowball into a fiasco like this. Chai, I also think you're right about the personality issue. I don't know about her relationship with her teacher, but you could tell noone taking the video or in the video cared very much for her. They were talking about her as if she wasn't there. Almost egging her on so they could catch her on camera and say "See, we told you she was bad". And as for "out of control", I've seen much worse, and have never had to, or known of any of my colleagues having to call in the police. That's just ridiculous.
What the cops did was intimidation, pure and simple, and absolutely unwarranted. The mom probably "should" be doing a lot of things. But we can't control what the mom is or does, we (in a school) have to take care of our own behavior, and we accept responsibility for whoever walks in the door. Bottom line. Yes, our job would be much easier if all the kids had perfect parents, but sadly (for them, most of all) they don't. Also cognitive delays and learning disabilities can be inherited. This mom might be struggling in her own life.... who are we to judge?
I heard she's at another school. Thank god, now maybe she'll get the help she needs in a classroom that is structured and taught by a person who likes to teach children such as this little girl. (We do exist

).
