Last month there were two legal developments in California that may have a substantial impact on youth sports: felony assault and battery charges against a 15-year-old high school water polo player for breaking an opponent's nose during a game, and a case allowed to proceed to trial next spring against the Pop Warner football organization because a coach failed to teach proper tackling. Not only are the events themselves notable, but the potential effects on purchasing insurance for youth sports could make those sports prohibitively expensive.
