The answer to that is simple:
ARM, TRAIN, AND LICENSE WOMEN!
(All the ranges around here have special “Ladies Nite” free shooting for women! And you can bet I schedule my days accordingly...hahaha!)
I've been arguing that for a long time. I've read about a lot women being shot and killed by their exes, but I've always wondered how many of the murdered women were armed at the time. I would guess very few to none.
