Stadium and team owners see drones as major league threat

On the Sunday after Thanksgiving, Sacramento resident Tracy Mapes drove to Santa Clara, flew a drone over Levi’s Stadium and dropped a payload of leaflets espousing his conspiracy theories over the San Francisco 49ers-Seattle Seahawks game. He then headed across the Bay to the Oakland Raiders game intent on doing the same. A year ago this month, a San Diego bartender crashed his drone into a fan at the Padres’ Petco Park. While Mapes was later arrested and the bartender was tracked down and fined, team security and local police were unable to stop the flights - whether with high-tech jammers or other means - for fear of violating federal law.
