Okay, I've had a question nagging at me since I watched the video of that trap. I doubt anyone will be able to answer it, but who knows?

When that antler was pulled off that deer it took off in a big hurry.

So was the deer startled? Or if a rack is close to, but not quite ready to drop does it actually hurt the deer to pull it off prematurely? Kinda like accidentally tearing off a scab?
