I'm a big believer in trapping and releasing mountain lions. Only I think they should be released in suburban Denver or L.A. I've heard the same frustrations vented by Californians who were afraid to let their kids outside because of lions in the area. But they can't do anything about it because urban environmentalists that don't have to live with the lions dictate policy to the people who do.
I lived on the north edge of Santa Monica for about a year once and knew people who lived in the canyons and in the hills not too far away from where I was. Cougars, coyotes, rats were a real problem for those home owners. But that's what exists in the hills and semi-rural areas around L.A. Actually it exists in all rural areas of the world. And don't even get me started on the Boulder types
