This is my take as well, what they have written is really dishonest. You could replace ring camera with mobile phone and make their same arguments and people would look at you like you are crazy.
Okay, let's do that:
> [paraphrasing] We've published an app that will live-stream your phone's camera to the police, you should use it.
...yeah, that actually seems worse to me.
> Lumumba said the city would only be able to access the devices when crimes occur in those areas.
Further, they haven't provided any details on how they will effectively control access, the area a crime would allow access to, how long the cameras could be accessed, or how they would handle false reports. Saying they won't abuse it isn't enough.
