From this link:
Los Angeles police say they are investigating a battery report from a fan who says Crawford sprayed water in his face during Game 4 at Staples Center. The report alleges Crawford used a water bottle to spray the face of the heckling fan, who was thrown out of the arena and later filed the complaint with police.
Is that even a thing? Can you get charged with battery for squirting a fan with water? Seems kinda silly to me
