Shooter incident at elementary school in Uvalde, Texas - 19 children and 2 adults dead

Think about it in practical terms
Who is being made to/asked to change their behavior in order to avoid the next horror?
Schools, kids, teachers, etc
Who is not really asked to change their behavior to avoid the next horror?
Gun owners, potential gun owners, gun sellers, gun manufacturers, legislators, nra, etc
Sure, but that's not what he said. If this is what he was getting at, then I don't really disagree with your sentiment. Several gun owners on this and other threads have talked about what they can do to change the situation, from training, to licensing, to registration etc. Now getting support for those things at a state and national level is a different challenge, but it can be done.
