“If you’re at the Badger game, you don’t have a reasonable expectation of privacy,” August said at the January hearing. “But if you’re in your backyard with friends having a barbeque, I think the last thing that you want to see is a drone.” That or a twister.

The bill would also limit the use of drones by law enforcement officials without a warrant, except for emergencies, like a search and rescue mission.

Kessler, at the hearing, gave a concrete example of what he didn’t want the government to know: “Which tavern did I visit last night and how many different stops did I make?” That could be a whole other column.

Just one of the state’s more than 700 registered lobby groups has taken a position on the bill: the American Civil Liberties Union of Wisconsin, which supports it. Several states have passed and many are considering similar bills.

“We’re afraid the technology is going to get ahead of the policy,” executive director Chris Ahmuty says in an interview. The ACLU believes law enforcement officials should need a warrant to use drones to snoop, “to protect what’s left of the Fourth Amendment,” against unreasonable searches and seizures.
