I've thought about this a lot as I see more and more reckless driving in the areas I live in. Surveillance is generally a net negative, but it's also bad when you see people speeding around schools, rolling through stop signs, and running red lights. We seem to have a worst of all situations where traffic is getting increasingly difficult to enforce, driving is getting more dangerous year by year, and we're terrified…
It usually takes about 5 minutes of driving to observe someone doing something that I would pull them over for. I don't think cops need all this automated surveillance, they just need to drive around and be proactive.
