I think hikermor's point isn't that bear encounters couldn't be dangerous or couldn't happen, but that there are far more likely causes of death and injury. Budget your resources accordingly.

Bear attacks are like dying at the hands of serial killers, getting taken out by the Sinaloa cartel and buried in the desert, or becoming a part of the statistics in a mass shooting. Getting a heart attack, dying in a car crash on your commute, getting a mortal reaction to an insect bite, etc. are all more likely. But we focus on the sensational stuff. We have long threads about bear attacks, but many people won't diet and exercise to save their heart.

By the way, chaos, obviously "tactical bears" are... black bears!!!
