Denverite: Hundreds of people crammed into a town-hall meeting on Wednesday to demand that Mayor Mike Johnston shut down Denver’s license-plate tracking surveillance system and stop working with the technology company Flock Safety.

Among them was an influential YouTuber who flew in from Austin  — a sign of how fights over surveillance technology across the U.S. have gone viral.

“I’m a privacy person. So the idea that you’re going to be watched everywhere that you go and there’s nothing that you can do about it is highly offensive to me,” said Louis Rossmann, a consumer rights activist and YouTube streamer. “But mostly I wanted people to realize that they can make changes in their local government … if they put their mind to it and if they actually show up.”
