My somewhat-obscured point was that anywhere you find or found whitetail deer in America, you would have once found the mountain lion. Including what is now Chicago. As deer begin to repopulate their former habitat (turning it into simply "habitat") then the lions will come.
I for one am glad to see it. Americans need a little more excitement. Not having been at the top of the foodchain since, oh, well, 1998, I can share with you that going through that transition can be a liberating and wonderful experience
People up here live with bears, wolves and a little further south lions cruising their yards all the time. Children aren't exactly being carried off in droves. Urbanites (I am a former one myself) just need to get used to the fact that just because you pave it over doesn't mean you aren't still in the wilderness (cue photo of coyote in downtown LA.)
If I had been next to that police officer as he raised his shotgun (pistol whatever) I would have given him a smack. Unless of course the lion was chasing
me.
