I'm willing to bet we're not seeing the whole video. Just the same, it does appear he had ample time to assess the situation. You would want to think that as a precaution, it would have been wise to just back out. His actions make me believe that he was determined to continue in that direction no matter what. Having that gun on board also makes me believe to think that he felt empowered to use it & claim self defense no matter how minimal the threat was. If he had a hoof print embedded in his helmet, that may be different. With that said, I wasn't there. Just the same, he exacerbated the situation, so he's still a fucker.
