I watched a special with some real biologists studying bears up in Canada, and I noticed that they had some excellent guides with guns watching their back. It is a shame that that delusional man dragged that poor woman down with him.
I have met people like this on hiking trails in eastern New Mexico and and in West Texas. Usually they are deluded urbanites whose perceptions of nature were shaped by Walt Disney movies that portrayed bears and cougars as "cute n cuddly" critters and grossly anthropromorphised them. They are often shocked when you tell them to be careful of mountain lions or black bears; the react as though you had just peed on their tofu and trail mix.
