If you don't want to watch, the 6-4, 220 pound wide receiver repeatedly whips what appears to be a pit bull or pit bull mix across the face with a belt multiple times as hard as he can, each blow accompanied by the dog crying out in extreme distress and pain.
The nine second video ends with Zamora kicking the dog to the ground, followed by another belt shot. An unnamed teammate videos the event quietly. There's no attempted intervention, no "Hey Ishmael, lay off man." The act wasn't spontaneous. The video's intent was to capture a dog being beaten and Zamora is so oblivious he doesn't even comprehend he's committing a crime on video.
