My DH was recently pulled by the class teacher to say that my DD had accessed graphic images of a horror movie on the internet during school time and showed them to other kids and terrified them and the school had had to write to the parents of the other children to let them know what had happened. My DD was distraught, as she has never been in trouble at school and was looking for a cartoon that lots of kids watch and a misspelling of the name of the cartoon brought up the graphic horror images. I was furious with the school and asked for a meeting to discuss the obvious safeguarding risk to the children. At the meeting I was expecting an apology for what had happened, but was instead told the head had spoken to my DD and she had told her that she showed the other children the images of the horror movie because she knows it from watching it at home. I made the head aware that I knew that this wasn't true in the slightest, as we have very strict parental controls in place on our computers at home and I know exactly what my child is watching. When we left the meeting, I asked my child if she had told the head that she had watched the horror movie at home and she got very upset and told me that she had told the head exactly what she told us, that she was just looking for the cartoon which she always watches. It is clear to me thst the head and the class teacher are lying to cover their backs and I am furious. How would you proceed if you were in this situation?
