*Shrugs* I didn't even know it was LP when I first saw the clip. I still thought it was a demonstarte of how NOT to acheive your objective (Actually, I didn't get the objective at all).
I don't disagree with the level of force. I do disagree with the way it was done - Flapping your arms aroubnd like a chicken and snapping a horse in the jaw with the metal clip on the lead is just not any way I would handle a situation, and I would not allow anyone else to handle my horses like that either.
I don't think the owner was that much better than than LP - He was giving more release, which was great, though the timing was off - but there were no 'phases', to quote Parelli. The horse took a step forward and SNAP gets the clip in the jaw. You ALWAYS need to start with the cue you want to end with - i.e. the smallest. Whisper, talk, yell and all that. Going straight to the strongest cue is only ok when you are physically in danger, and I didn't see that once through either of the videos.
