Surely you jest.
I’ve never used OC on a bear, but I have on persons in my professional capacity. I have never, and will never use OC on something or someone that is posing an imminent lethal threat. If I think I’m about to be killed or dismembered- lethal force is the only option. Plus, every time I’ve ever deployed OC, I end up getting some on me as well. I can’t imagine how bad it would be with a huge fogger spray. I’ve watched some videos of people trying to juggle a pistol and a can of bear spray at the same time. That’s a great way to be ineffective with both. There’s a reason most LE agencies have a policy that doesn’t allow you to have both lethal and non/less lethal deployed by the same person at the same time.
