 If people see a bear they should stay away from it and around here we have black bears so what they need to do is make a lot of noise and they'll usually run off. If they don't run off just slowly back away I believe that's what fish and wildlife would tell you to back away but usually noise is the best way to keep them keep away from them. Don't feed them obviously around your houses make sure that your trash is put up that'll keep it from getting into your trash and such but generally the ones I've run into the experience I've had with them is just making noise and they usually take off.
