“Dangerous” is a relative term. Here in rural central Missouri, I have seen cougar. I have seen what are left of deer that is consistent with being killed by cougar. But cougar are only dangerous to people who cannot defend themselves in the rare event they should be attacked.
When I walk the dog at night along a private road in the woods, I carry a side arm. One of the reasons that cougars are “dangerous” is where laws prevent people from being properly armed. It seems there are too many politicians whose policy of achieving victory over danger of any kind is to be defenseless.
