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.
