From what we've read here, I would hesitate to base any opinion on the attitudes of the mother, too. I've seen too many instances where parents have blamed the school, teachers, administrators, coaches and anyone else they can think of because their child was caught doing something he shouldn't have been doing. I even had a parent swear to me that her child would NEVER lie after he lied right in front of me.
I would like to hear the teacher's/police side of this story but, as noted elsewhere, the unions and board of education are not likely going to allow that to happen unless and until the case winds up in court.
