One mountain biker is killed, another injured by a mountain lion in
Orange County, California...The lion is still on the loose.

"on the loose" ?

As in, trying to live where it has for tens of thousands of years
while idiots keep riding around in its habitat?

Idiot quote of the day: "This mountain lion was hunting and I don't
now why. I've never seen behavior like that. It was just unreal."

Here's why: It was hungry and in its turf. What is so unreal about
that?

It's unusual because Mountain Lions, as a species, do not hunt humans. This
lion is different. Around humans, they have been timid, shy, and reclusive.
