Drones make policing too easy, and will make police excesses more common. The CHP is considering using drones to police California's freeways. What this will mean is more tickets given out more frequently. Now, when you were pulled over before, the CHP Officer had to work a bit to get you, and give you the ticket. That means when a person was hauled in front of a judge, you could safely assume they were guilty. Now, they won't have to do anything. Just ID a speeding vehicle, zoom in and bam, ticket sent. They will have the same credibility as though they physically pulled you over. (at least for a while) So, say the detection software has a bug and 65mph reads as 72mph. You get a ticket and have a hard time fighting it. That's one instance. Here's another, if the various police departments had a certain light filter, they could easily scan whole neighborhoods for the bleed-out of UV grow-lamps that pot growers use. Right now the only cost effective way is to drive around or use a helicopter. Driving isn't very efficient, and the helicopter is cost prohibitive. A drone could be use for other things, and get this done as almost a side job. It may not seem like very bad things, but these two (there are more, just think about it some) can give way to much more police excesses. Their job shouldn't be easy. The hunt for evidence keeps them honest, and forces them to follow procedure. Those are good things.
