Im not logging into FB to see this but I'm guessing this the vid of the guy that glocks the mountain lion at a few yards?
Scary situation and I may of acted similar however I don't think the cat "pounced" like he said as it was in the same exact spot after he picked the camera back up. Also his "talking" to the cat to back off is a fricking joke. It's a wild animal it doesn't understand English and won't be intimidated by talking volumes. Yell at that thing, roar, make a scary noise, belt out your best low and loud deathcore impression or something.
