This discussion really brought me back to my high school days when one of my dear friends got kicked out of school for going at a guy in shop class with a saw. My friend was so sweet and never violent to my knowledge, but he was
very different than other kids in those days. I think he was being teased or bullied. He ended up okay though because he had already found his community, a community of support through his club activity/ extracurricular activity. Which included kids, parents, teachers and other adults. His life went on and he continued to connect with other opportunities despite being expelled/ longterm suspension.
It sounds to me like EC may not have found that community. It worries me that we may have a much higher rate of young folks who have not "found their community" because they have been staying at home. And returning back to life can be a slow process, perhaps especially so for teens who are often uncomfortable in their own skin anyway and still finding themselves. Let's hope schools are investing in more counselors. And metal detectors! (Sheesh that's a pretty big school to still not have a metal detector).
