It's easy for people who've never been bullied or in the same situation as Casey to say "Yeh, he shouldn't have used violence", "Yeh he overeacted". I've been in a similar situation. When you're pushed and pushed for years, afraid to go to teachers for fear of making it worse, it gets to a point where you just want it to stop through any means. It can create intense hate and you do flip. You react with a very primal instinct and you don't think. It's very hard to communicate that feeling to someone who had a cushty, no problem life through school. I didn't and it doesn't end until you stand up to yourself. I appreciate everyone has their own opinions but please don't judge him when you have no idea what it's like. I can empathise completely with this kid and, good on him!
