There seems to be a very sizable number of people who believe cameras should not be used as evidence because the footage could implicate an innocent person or be misinterpreted. OCR can be wrong, just as a person can make a mistake or fat-finger a data entry, and so on. We should absolutely expect law enforcement to understand the gravity of their actions and use this technology appropriately. I don't agree that getting rid of cameras is the answer here, far from it.

Right, the "OCR" issue here is what I'm interested in --- Flock's vision models just straight-up making mistakes. There's a whole other issue of police not being well-trained in how to use these things, which leads to problems like "indict the first Dodge Durango we can find", but those are police policy issues more than they are ALPR issues.
