Great idea! Trained guard dogs, paid shooters and each field team carrying sprays in a VERY accessible holsters(4) and if they want a hand gun/ rifle that is again, accessible, hard to get to anything during an attack, it would be for a break off from attack(s). By " of duration ", I took it to mean that each attract was long, to kill, not to stun, as in a defensive attack. These things are going to happen though, we live with bears and we just can't be prepared for everything. Condolences to all involved, family, friends of this beautiful woman. So sad for her husband! 🌺
