Last July, San Jose issued an open invitation to technology companies to mount cameras on a municipal vehicle that began periodically driving through the city’s district 10 in December, collecting footage of the streets and public spaces. The images are fed into computer vision software and used to train the companies’ algorithms to detect the unwanted objects, according to interviews and documents the Guardian obtained through public records requests.
I don’t think the idea is to bring criminal proceedings against people. Not sure what they do in San Jose but in cities I’ve lived, homeless people are essentially immune to fines or criminal charges because police know they can’t/wont pay anything. So they go force them to move and throw away their belongings if they can’t or don’t take them in time, but do not arrest or ticket these people.
