I can equate an angry bear with human monsters, I can equate a laid back so called tame bear with human Monsters. Both act on impulse, and instinct. To me bears and human Monsters are just gigantic Pit Bulls.
The man that raised tame bears for the movies for 40 years died when a well tamed bear he had raised from a cub for no reason went off on him. Goggle bear attacks against humans and see just how horrific it can be.
There is a small amusement park up north that for at least 80 years has drawn in customers with their bear act. There are perhaps 5-6 that are trained to ride bicycles and even eat icecream from a trainers mouth.
A good friend of mine was born and raised about a mile from the Park and tells of 3-4 times a year when some of the bears got loose in the spring and the police called everyone in the area to not let the kids outside ----Yippie, another day home from school.
