If Jerry Jones was able to spit on those black students from that distance, he must have been a virtuoso spitter. If spitting had been an athletic event, he would have qualified for the Olympics.
I'm willing to judge Jerry Jones as a scumball based on the other facts about his adult life in your article. But this photo seems to me to indicate that he was a morbid curiosity seeker, rather than an active participant. Maybe that's almost as bad. There is something voyeuristic in the intense way he is staring at the scene.
