If he would have only used bear spray, the bear would be alive and the warden would be either mauled or killed.
But the bear would be alive!
The message to tourists is that bear spray keeps the bears alive! But bear spray MIGHT BE 90% effective in stopping a bear attack. Might be.
Of course the sprayed bear needs some distance to halt its charge and might accidentally skid to a stop on top of the sprayer ... at which point nature will kick in, spray or no.
“But bear spray MIGHT BE 90% effective in stopping a bear attack.”
A gun may only be 50% effective. My understanding is their CNS must be completely destroyed to get them to instantly keel over. I’ve read where they will run an additional 100 yards or worse yet kill the shooter after their heart was blown out.
My opinion is to shoot first, spray later if it keeps on coming. At least you can reassure yourself you tried everything while being mauled to death.
