Guard dogs trained to attack persons in school with assault weapons could save so many lives. If they also could smell drugs, that would be another plus. Dogs also are of the pet class and pets are known to be beneficial to people of all ages.
Why is this important?
Lots of people have guard dogs or watchdogs! Imagine a dog who is trained to attack a wild student/crazy who is carrying an assault weapon? A pair or trio of dogs should be able to save lots of student lives. They could also be mascots, grade by grade. Imagine these dogs also can smell drugs.
