The United States Postal Service has a surveillance program that tracks social media posts for law enforcement, and no one can say why:
The details of the surveillance effort, known as iCOP, or Internet Covert Operations Program, have not previously been made public. The work involves having analysts trawl through social media sites to look for what the document describes as “inflammatory” postings and then sharing that information across government agencies.
“Analysts with the United States Postal Inspection Service (USPIS) Internet Covert Operations Program (iCOP) monitored significant activity regarding planned protests occurring internationally and domestically on March 20, 2021,” says the March 16 government bulletin, marked as “law enforcement sensitive” and distributed through the Department of Homeland Security’s fusion centers. “Locations and times have been identified for these protests, which are being distributed online across multiple social media platforms, to include right-wing leaning Parler and Telegram accounts.”
When contacted by Yahoo News, civil liberties experts expressed alarm at the post office’s surveillance program. “It’s a mystery,” said University of Chicago law professor Geoffrey Stone, whom President Barack Obama appointed to review the National Security Agency’s bulk data collection in the wake of the Edward Snowden leaks. “I don’t understand why the government would go to the Postal Service for examining the internet for security issues.”
I mean, scraping social media takes only a modicum of technical skills. In the last year I've written software that can scan Twitter and run detailed sentiment analysis on keyword-based searches. But I'm not a government agency with arrest powers. Or, you know, a constitutional mandate to deliver the mail.
Weird.
