I read all this yesterday, and I'll be the odd one out and say, "I ain't buying it." This school says they fly the flag. That they pledge allegiance. They also say (and usually schools don't say anything due to sue happy American parents) that the kid was supposed to be doing something else, when he was drawing.
I find the school believable, in this case.
There are more than a few, "Junior does no wrong" kind of parents in this country.
