Federal investigators obtained court-ordered subpoenas for any YouTube viewers who watched tutorials on mapping with drones and augmented reality software.

The subpoena included names, addresses, telephone numbers, and browsing history for Google accounts for at least 30,000 people, tracing traffic to the relevant videos for the first week of January 2023.

The government also wanted the IP addresses of non-Google account owners who viewed the videos.

"There is reason to believe that these records would be relevant and material to an ongoing criminal investigation, including by providing identification information about the perpetrators," the authorities claimed, according to Forbes.

Google was also told to keep the request secret until it was unsealed earlier this week. It's unknown if Google complied with the subpoena.

But that wasn't the only case of the FBI trampling on privacy rights.

From Forbes:

In another example, involving an investigation in New Hampshire, the Portsmouth Police received a threat from an unknown male that an explosive had been placed in a trashcan in a public area. The order says that after the police searched the area, they learned they were being watched over a YouTube live stream camera associated with a local business. Federal investigators believe similar events have happened across the U.S., where bomb threats were made and cops watched via YouTube.

They asked Google to provide a list of accounts that "viewed and/or interacted with" eight YouTube live streams and the associated identifying information during specific timeframes. That included a video posted by Boston and Maine Live, which has 130,000 subscribers. Mike McCormack, who set up the company behind the account, IP Time Lapse, said he knew about the order, adding that they related "to swatting incidents directed at the camera views at that time."
