Amazon’s Ring devices are not just personal security cameras. They are also police cameras—whether you want them to be or not. The company now admits there are “emergency” instances when police can get warrantless access to Ring personal devices without the owner’s permission. This dangerous policy allows police, in conjunction with Ring, to decide when access should be granted to private video. The footage is given in “cases involving imminent danger of death or serious physical injury to any person.” The company has provided videos to law enforcement, without a warrant or device owner consent, 11 times already this year. This admission comes in response to a series of critical letters from Senator Ed Markey (D-MA). Markey chastised the company over many of the same privacy problems that EFF has brought up, including the far-reaching audio capabilities of Ring devices, and the company’s refusal to commit to not incorporate facial recognition technology into their cameras.
I don't have more information on this particular company's dealings with law enforcement, but I certainly think it's reasonable to be concerned.
I also think most cars can't be stopped dead with a traffic cone, so these protesters are highlighting the unpredictable and sometimes dangerous behavior of these vehicles in mixed traffic. While I'm sure the folks involved would like to see steps taken to address cars and transport infrastructure more generally, it's hard to see why you would call this 'hypocritical'.
