It’s funny that people are using ear pepper spray on people. The kind that you use for people is way stronger. Bear pepper spray is so weak as to be useless against a grizzly bear and lack bears usually don’t bother people so they never need it. But if you need protection against bears use the stuff cops use on people.
Mind you I'm taking the "bear pepper spray" thing from people who were getting sprayed. If bear pepper spray really is that weak, maybe it was regular pepper spray, or they added something to it, and so people assume it must be for an animal. There is at least one fellow in hospital with possible permanent blindness.
