...I didn't because I'm a jerk.
This jerk wanted to capture an alligator devouring a bobcat. If he had wanted to alarm it, he could have, although maybe he couldn't because he was just so "breathless" from the graceful movements of the stalking 'gator.
Personally I can not STAND all the videos from Planet Earth, National Geographic, or this backyard Crocodile Dumb-dee that show animals being hunted, eaten, starved, dying.
One of you morons behind the camera DO SOMETHING! Nature has the advantage. There will be plenty of death and pain and despair without you standing there letting it happen for the camera.
I know...I know...then there would not be a show. I don't care. I hate all those shows.
