wasabe64, Unicorn, & Rich: Thank you for your suggestion of bear-repellant and the additional information regarding Canadian law. I didn't even know pepper spray was made of this strength.
Sotto: Thank you for the humor. This sounds like a very potent weapon,,,,,,,,200 years ago. I'm sure it could indeed kill a bear or cougar but not many of us would have the required skill for a single attempt spearing. After one attempt, if the animal is not dead, you are sure to be.
Nikola Tesla: I like your idea, but I'm afraid one would have to be too precise in a situation that more than likely would happen far to quickly to take accurate aim.
Cryptoguru: Not sure what a human who was stopped for a simple traffic violation has to do with a flesh-eating beast who has no concern of your life but rather wants to eat you. These wild animals have zero respect for man, in or out of uniform and make no distinction about those they choose to attack. Contrarily, that man's face that you shined your light at had to respect the fact that you are an officer. If you were off duty, and simply shined that same light in that same guys face, he would probably retaliate. Fortunately for you, he showed respect.
