I was at an Angels playoff game in the 70s. When the Angels won, the fans got excited and leaped over the fence and cavorted around the field. They weren’t hurting anything; they were just leaping and clapping and running. APD brought out the billy clubs and beat a bunch of them up in an effort to control the celebration. It was completely unnecessary and disgusting. (And they were all white fans, by the way.) Overreaction is a long tradition with them and not necessarily race related.
