In light of the information coming out about the GA school shooter I’m more fired up than ever about a situation my son is involved in at school. A boy in my son’s grade has accused my son of bullying him half a dozen times. Half the incidents have been proven false via video footage -my son was not even present 2 of the three times. Two incidents involved locker room jokes about deer testicles and “your mama so fat” between his friends that this kid wasn’t a part of but he overheard them and found it offensive. The last incident involved my son breaking up a fight with this student and an even smaller student. A week later this boy pulled a knife on my son at school and threatened to kill him because his dad is military and has trained him to kill. The threats of physical violence have continued this year and this kid has a strong infatuation with guns (presentations on guns, projects about guns and talks about guns constantly) The school’s position is “Your son is so big, there is no threat,” “Your son is literally a foot taller than this kid,” “This boy is on the spectrum and doesn’t always know what he is saying,” “I’m pretty sure your son could handle himself if he felt threatened.” 
I am livid and today threatened involving law enforcement if it continues. I’d rather be wrong and considered an overzealous mom than right and students including my son get hurt. 

What do you think and how would you handle this if it were your child?
