kevonionia,

As an alternative to deadly force, the National Park Rangers now pack a Tazer (on the other side of there body from their handgun).

They have an appropiate use in defense situations - generally when trying to stop or subdue one individual human. Weight 18 ounces.

Any stories out there to share on shocked bears? I would be interested to see a Youtube video of such an experience in the field. How about one of a bear getting sprayed?
