I thought they closed the entire park once that video surfaced.. if after that video they still only closed one trail, yes that is actually a bit laughable..
Nobody ever suggested leaving the cat in the park permanently. Why not just close the entire park (closing one trail was laughable) for a few days, monitor the situation, and see what happens? The lion almost certainly would have wandered off on his own to find a more suitable territory. If not, I think most people would have considered relocation to be the most sensible plan.
Variations on this situation will continue to occur as long as there are big cats in the Santa Anas. This didn't seem like a great long-term solution.
Seacrest out...
