She is very brave to protect the young ones I take my hat off for her.
On another note, mass shootings as written didn't occur because from a young age people learned about the gun, how to use it and what can it do. Nowadays children are too "defended".. if your kid falls from a swing, don't tell him "don't go on swings" let the kid learn what the fall from swing means and they will stop falling! We learn by experience. :)
I let my kids fall down and they had to pick themselves up and brush themselves off...We also went hunting and killed livestock on our farm so my children knew what dealth looked like and smelled like. Many people have no idea what it is like to kill something with a gun. All people know is the clean fake deaths on video games....Seeing and experiencing the destructive nature of guns teaches respect and the dangers of handling dangerous tools carelessly. Farm kids had to work with not just fire arms but chainsaws, tractors, equimpement if handled carelessly could kill them or someone else...most kids today only know how to handle digital equimpment.
I am glad you are raising your kids as it should be. So they are prepared for life! You are definitely right, today everything is about protecting kids and putting them in bubbles when in the same time real world isn't like that...
