It's almost like it's really hard to stop a mass shooter once they've started mass shooting, they picked the time and place and have a gun and their goal is indiscriminately killing as many people as possible as fast as possible. There is literally no response plan for this, let alone one that can be done on the fly by teachers and children during school let alone like. You have to do things that make people want to mass shoot less, which is actual work, but this nonsense seems like it would just get more people killed.
