Ed, I think you are right about what likely happened. The most aggressive bears were shot. The friendliest, most entertaining bears were selected to keep in the parks for the amusement of park visitors, and the other bears were exiled. This is a classic example of human selection and it has surely had genetic consequences.
Darwin wrote about how human selection (of the traits of species) is conducted for our own good, while nature selects for the good of each specie that it tends. He warned of the awful consequences of taking over for nature. That was in 1859. We have now seen the result of ignoring that part of his words. For anyone unfamiliar with Bill McKibben's work, it is this that he has called the "end of nature."
We have made a mess of things for the bears (and other species selected by nature) and for ourselves.
If Darwin is also right about what eventually happens to a specie like ours, then we are doomed, even if life itself survives.
The bears are all innocent.
