Protesters fear these “smart lampposts”—streetlights equipped with sensors and cameras, perched high above the most densely populated areas of the territory—may have surveillance and facial-recognition capabilities. It’s not been proved or debunked, but the threat is compelling enough that protesters have toppled 20 such lampposts since their rollout in July. “I think that [smart lampposts are] just a trick the government is using to spy on us. It invades our privacy,” a protester who gave the name “Nick” told the Hong Kong Free Press. Nicholas Yang Wei-hsiung, Hong Kong’s secretary for innovation and technology, has denied the claims, the South China Morning Post reported, dismissing them as “conspiracy theories.”

In a Twitter thread posted last week, Chris Lau, a reporter with the South China Morning Post, filmed protesters dismantling a lamppost. Holding umbrellas, a handful of them obscured the person holding the saw, while others circled the group, likely lookouts for intervening police. In the footage, sparks fly and protesters exclaim, then cheer, when the lamppost falls. Last week, TickTack Technology Limited, a local firm that was supplying parts for the smart lampposts, announced that it was terminating its contract with the Hong Kong government after furnishing supplies for only 50 of the 200 posts it promised. TickTack representatives said in addition to the property damage the company has suffered, its employees have received threats. (TickTack did not immediately respond to a request for comment from The Atlantic.)

The Hong Kong government has acknowledged that the lampposts have enough hardware to spy on citizens, but says protesters’ fears are unfounded. In July, as the first wave of lampposts were installed around the region, federal officials promised to disable some surveillance features, including license-plate recognition and continuous audiovisual surveillance. Tony Wong, an assistant government chief information officer in Hong Kong, said in a recent press conference that the posts aren’t capable of the invasive facial recognition deployed in China.

That hasn’t stopped the buzz saws. On Facebook, Reddit, and Twitter, protesters have uploaded photos of the sawed-open guts of lampposts. It’s risky to take crowdsourced information at face value in an environment so rife with propaganda and misinformation, but the posters speculate that these lamp innards reveal tracking technologies similar to the surveillance systems the Chinese government uses as part of its repressive campaign against the Uighurs, China’s Sunni Muslim minority group.

Of course, “proving” that the smart lamps use the same repressive technologies wielded against Uighurs requires dismantling and analyzing Chinese surveillance equipment, not just Hong Kong’s. Pictures of RFID cards and ethernet cables don’t demonstrate a direct connection. But suspicions of surveillance are compounding Hong Kongers’ anxieties over the proposed extradition policy. They fear that easier extradition is a step toward second-class citizenship in a Chinese-controlled state.
