This is just so upsetting, I'm still trying to process how something like this can happen in a school setting. As a parent myself, it's terrifying to think about my own child being in that situation. I know we need to stay calm and let the authorities do their job, but it's hard not to worry . I've been hearing about active shooter drills and lockdowns for years now, and I'm starting to feel like these measures aren't doing enough . We need to find a way to make our schools safer without putting everyone on edge . The fact that this incident was isolated is a big relief, but we can't let our guard down yet .
