It's hard to argue against them saying national security, because they're never going to release anything hard and fast. The US government definitely has a track record of waving it around as a blank cheque though (for a more recent example the TikTok U-Turn) However, this quote in particular feels like scaremongering, with vague hand waving about a drone with a camera doing exactly what you'd expect a drone with a camera to be able to do, but with a few more vague accusations that I'm not convinced by (If a drone can remotely measure heart-rate that's very cool though and I'm interested in how): "“DJI drones and the surveillance technology on board these systems are collecting vast amounts of sensitive data — everything from high-resolution images of critical infrastructure to facial recognition technology and remote sensors that can measure an individual’s body temperature and heart rate,” Commissioner Carr said in a damning statement."
