The Air Force’s Office of Inspector General faulted the Air National Guard for how it conducted seven RC-26B reconnaissance flights over public demonstrations following the death of George Floyd in early June.

In an August report of investigation, obtained Friday by Air Force Times from the Office of the Secretary of Defense, the IG said the National Guard Bureau didn’t get proper permission to use reconnaissance planes in law enforcement matters.

Although some members of Congress expressed concern that the flights may have collected personal information on American citizens, the IG said that did not happen. The planes were only capable of collecting infrared and electro-optical imagery, the report said, and its equipment is not detailed enough to distinguish people’s personal features.

Protests began across the country on May 26, one day after George Floyd died during an encounter with Minneapolis police. From June 1 to June 4, the report said, the Air National Guard flew RC-26 planes a total of seven times over Minneapolis, Phoenix, El Dorado County, California, and Washington, D.C.
