I just had a mental image of the refs. "A fan of the home team in the stands just punched a fan from the other team. 15 yard penalty on the home team." Pretty ludicrous.
I guess the one thing the SEC has done is to give the member schools a powerful $250,000 incentive to install a hi def camera system around the top of the stadium to watch for who the perps are so they can be dealt with by law enforcement. A control room and a few video watchers with some basic video review software should do the trick.
