Pairs of dogs. School kids will feel better just seeing them in the hallways. They can pet them throughout the day. The comfort. Knowing they will run INSTANTLY to take down the shooter. I don’t understand why no-one has thought of this. Pairs of dogs. Multiple pairs. Trained to smell gunpowder and signal every thug’s gun. Oh yeah, so simple an addition to all our vulnerable places like schools and worship zones. Pairs of trained attack DOGS. But dogs able to be touched and loved by the young (and old) they protect. How much can it cost? Against the cost of ONE child’s life? Add in the value to the childhood that can be made to feel a little safer, the child able to relax and more able to learn.
