A California man who has been arrested several times for recording police from the ground has now taken to the airways, using a drone to watch the watchers.

"It's to try to promote transparency," 42-year-old Daniel Saulmon told a Los Angeles news broadcast.

The Southern California man's footage is posted at Mistakenbacon.com. Recent recordings show a drunken-driving checkpoint and traffic stops. Titles of his footage include "Torrance Cop is Scared of My Camera," "Federal Agents Threaten Photographer," and "DJI Cop Block Drone On KTLA Evening News."

"If there's police activity in my area that is close by, I generally will go and try to record and document whatever I see," said Saulmon.

Saulmon did not immediately respond for comment.
