In a recent post I pointed out various ways that license plate recognition devices could be combined with other databases to invade privacy.

One obvious use for ALPR that I did not mention is speeding tickets. If you鈥檝e gotten from point A to point B in less time than would be possible at the speed limit, it would be simple to have the system automatically spit you out a citation. Surveillance drones could also be used for traffic enforcement.

But speeding tickets, unlike many other enforcement mechanisms, are politically touchy. Support for a drones program in Houston after a senior law enforcement official allowed that the technology could be used for traffic enforcement. When I first started working for the 老澳门开奖结果 in the summer of 2001, before 9/11, we were invited to submit an op-ed on red-light cameras to a business magazine. After it was published, we were swamped with supportive letters鈥攕ome including checks鈥攆rom people irate over this technology. Based on what I see and hear, red light and automated speed cameras continue to generate a lot of resentment.

It鈥檚 an interesting question why the public resents enforcement of traffic laws more than other laws. The answer probably has to do with the fact that enforcement of speeding laws is capricious鈥攖hose who violate speeding rules are punished so rarely and inconsistently that it becomes effectively random. The common use of speed traps as a also undercuts the legitimacy of safety efforts, and speed limits have an inconsistent relationship to genuine safety, with very wide, straight roads often bearing speed limits far below the safe driving speed for those roads.

For better or worse, speed limits are one area where our laws are out of synch with behavioral norms. Although almost everyone supports enforcement against genuinely dangerous behavior on the roads, many people routinely violate speed limits who would almost never break other laws. As I have discussed before, social norms are often at least as important as actual written law in governing behavior. When the two don鈥檛 line up, the results can be interesting.

Technologies such as ALPR and drones mean that it is, or is about to be, technologically possible to engage in 100% enforcement of certain laws. That may sound good at first glance, but I predict it will be a wrenching process in many ways. I鈥檓 not usually one to spout ancient Latin quotations, but Cicero knew what he was talking about when he Summum jus, summa injuria鈥斺渆xtreme justice is extreme injustice.鈥

While it鈥檚 often said that 鈥渢he law is the law,鈥 there is always a complex interplay between social practice and written law鈥攁n ongoing negotiation between the two, which depends upon a bit of 鈥減lay in the system.鈥 Every complex society has unwritten laws that everyone is nonetheless expected to follow, and . And most laws have gray areas and extenuating circumstances where human beings with good judgment would choose not to enforce them.

Automated law enforcement, however, blows all those subtleties out of the water.

To take just one tip-of-the-iceberg example, a friend of mine was sitting at a red light when an emergency vehicle approached from behind. To get out of the way he had to pull to the side and forward, into the intersection. As he waited for the vehicle to pass, a strobe light flashed, and a week later he received a red-light ticket in the mail. No human law enforcement officer would have written that ticket.

In the case of speed limits, considering Americans鈥 ambiguous relationship with those laws, something would have to give. If all speed limits were enforced 100%, Americans would have to change their behavior drastically, or the laws would have to be changed, or many people would experience the system as oppressive and resent it. The most likely outcome: some combination of the three.
