You know, this actually raises an interesting question that hopefully BioBear will answer if he's still around.
So, folks argue endlessly in regards to what is "enough" for Bears, often to the point that even the effectiveness of powerful cartridges are called into question, yet Bear Spray is 92% effective.
My question is, how does Bear Spray manage to be so effective without causing permanent injury to the bear? Honestly, how is it that Bears are supposedly able to shrug off having large caliber hot pieces of lead piercing their bodies, smashing through bones, and penetrating their organs along the way, yet getting some hot gel sprayed into their eyes/nose/throat is 92% effective?
Is Bear Spray far less humane than I've been lead to believe, like getting sprayed with corrosive acid or causing such agonizing pain and unspeakable terror to the animal that it loses all ability to fight?
Does it temporarily blind them? And if so, how do they get it out of their eyes? What's to stop them from blindly charging over the edge of a cliff and onto some jagged rocks? Has this stuff ever been thoroughly tested on bears in captivity to confirm that it doesn't cripple them for life? Has anyone ever observed bears in the wild after they've been sprayed to see if they're even capable of getting it out of their eyes? Whether it causes prolonged irritation which may cause the bear to scratch at their eyes until they've become infected?
It just baffles me that apparently bears are so fierce that absolutely nothing short of an instant-kill-shot will stop a bear, yet a can of spray will, despite supposedly being totally humane. You'd think for it to be that effective then it would have to be excruciatingly agonizing, which to me seems far less humane than simply shooting it dead.
