You forgot to mention that maybe this teacher has 30 years seniority and anything less than 1st degree assault and the teachers union is going to circle the wagons on her behalf. But even so, I know that it is possible that this may have went down exactly as you have described it, but its not as though you have a mountain of evidence. Are you not even mildly curious as to what the teacher has to say about this, or does her version of what happened mean nothing at all? I mean I guess we can try her and convict her on this site with second hand information from a little kid, but it might take a little bit more than that in the real world. If I was you I would continue to believe what I believe, but I might lower my expectations a little bit as to whether I could convince others to just fall in line.
