In wake of the MLB opening day issue of opponent fan beaten in the parking lot after a game..... I noticed a lot of police/uniformed security in the parking lot after tonight's preseason game in SJ. In past seasons, I've seen 1-2 policeman inside the arena near the entrance, but tonight there was one guy watching the exit doors and two more on the outside watching fans leave. And (mobile) security near one end of the parking lot watching the comings/goings. Now the Sharks and Ducks are in state rivals, but I've never seen this much security post game. Would not be surprised that the NHL and/or the Sharks have been proactive for known rivals with mobile/following fans in wake of the beating.
