It was a normal story on a normal day, when Next was out shooting some video, and then we realized someone was shooting video of us.

Producer Cody Broadway was out when he spotted a drone on the pedestrian bridge over Interstate 25 near Evans.

The problem wasn't so much that you were filming us, random stranger; It’s the fact the drone was flying over a highway.

The Federal Aviation Administration told us that, assuming the operator was a hobbyist, the drone is supposed to fly “in accordance with a community-based set of safety guidelines.”

And the Academy of Model Aeronautics Safety Code says that operators “shall avoid flying directly over unprotected people, vessels, vehicles or structures and shall avoid endangerment of life and property of others.”

And a moving vehicle counts as unprotected.

If you see a drone flying where you know it shouldn’t be, who do you call? Well, that’s a difficult question to answer in what seems to be a classic case of “Go ask your mother.”

Denver 911 told Next to call the FAA, but the FAA told us to call 911.

The FAA also recommended calling the Flight Standards District Office. In Denver, the number is (303)-342-1100.

Denver police only investigate drones over parks and parkways, as that’s against city ordinance.

And if you’re a drone hobbyist who wants to avoid breaking the law, here are a few more links from the FAA on what you need to follow.
