Fans who hear the whirring sound of a drone over a stadium might see it as a nuisance but law enforcement has long viewed those aircraft as a potential weapon of mass destruction. This was reported by Qazaqyia.kz citing Associated Press.

With the World Cup about to kick off, security is heightened and there's a zero-tolerance policy for drones over or near stadiums during the 78 matches in 11 U.S. cities.

Authorities have ratcheted up counter-drone measures used at the Super Bowl and other major events, while Congress has given law enforcement broader authority to electronically disable drones or shoot them down.

"The war in Ukraine has become a real-world testing ground for drone technology, and if there is one threat that keeps me up at night, it is from drones," New York Police Department Commissioner Jessica Tisch said.

Congress just gave state and local law enforcement the green light to take control of a threatening drone or even shoot them down if needed in December, though the first option will be to disable them electronically and land them safely. Key federal agencies already had that power.

The Federal Aviation Administration will restrict the airspace around and over crowded stadiums for World Cup games and fan events — much like it has done for years around NFL and Major League Baseball games. Violators can face fines up to $100,000, see their drones confiscated and even face criminal charges for flying within three miles of one of the games. But those penalties likely wouldn't deter a determined terrorist.

The FBI has spent the last seven years building up its capability to deal with drones by investing in the technology needed to quickly identify drones and take control of them, and authorities have been using that already at major events. The bureau also provided counter drone technology training this year to law enforcement in all World Cup host cities that taught them how to recognize dangerous drones and respond.

The military has also developed counter drone lasers like the ones used along the Mexican border earlier this year and other systems to shoot down drones, but the FBI is not planning to do that during the World Cup because of the dangers involved with the wreckage of a drone falling over a major city.
