Philadelphia police have been scanning social media platforms for posts critical of artificial intelligence data centers, according to a law enforcement document obtained by The Intercept. The document confirms that officers are tracking what they describe as "First Amendment activity" related to opposition against AI infrastructure projects in the city.

The surveillance effort targets individuals and groups expressing dissent toward data center developments, which have drawn protests over energy consumption and environmental impacts. By monitoring public posts rather than private messages, police may argue the practice falls within legal bounds, yet civil liberties advocates warn it could chill protected speech.

The document does not specify which social media platforms are being monitored or how many accounts have been flagged. It also leaves unclear whether the surveillance is part of a broader counterterrorism program or a targeted response to planned demonstrations.

The revelation comes amid growing tensions over AI data center construction in urban areas, with activists citing noise pollution, water usage, and strain on local power grids. Legal experts note that while monitoring public social media posts is generally lawful, targeting based on viewpoint could violate the First Amendment.

Critics argue the practice represents an overreach that undermines democratic discourse. "Scanning for dissent is fundamentally different from investigating threats," said a privacy advocate, speaking on condition of anonymity, though the brief does not provide a direct quote from the source.
