Just 2 cents from someone who has been sprayed more times than wanted. There is a reason LE transitioned to the Taser. It's a better tool in the legal use of force continuum. I've seen people cough, gag and puke and I've seen people smile, unaffected after being doused with pepper. Even those who cough and gag can fight through it with appropriate adrenaline. I have zero confidence in pepper spray against any bear. It's a roll of the dice. Once pepper spray becomes airborne, it's also non-discriminatory.
