An interesting aspect of this, especially their blog post (https://malus.sh/blog.html ), is that it acknowledges a strain in our legal system I've been observing for decades, but don't think the legal system or people in general have dealt with, which is that generally costs matter. A favorite example of mine is speed limits. There is a difference between "putting up a sign that says 55 mph and walking away", "putting up a sign that says 55 mph and occasionally enforcing it with expensive humans when they get around to it", and "putting up a sign that says 55 mph and rigidly enforcing it to the exact mph through a robot". Nominally, the law is "don't go faster than 55 mph". Realistically, those are three completely different policies in every way that matters. We are all making a continual and ongoing grave error thinking that taking what were previously de jure policies that were de facto quite different in the real world, and thoughtlessly "upgrading" the de jure policies directly into de facto policies without realizing that that is in fact a huge change in policy. One that nobody voted for, one that no regulator even really thought about, one that we are just thoughtlessly putting into place because "well, the law is, 55 mph" without realizing that, no, in fact that never was the law before. That's what the law said, not what it was. In the past those could never really be the same thing. Now, more and more, they can. This is a big change! Cost of enforcement matters. The exact same nominal law that is very costly to enforce has completely different costs and benefits then that same law becoming all but free to rigidly enforce. And without very many people consciously realizing it, we have centuries of laws that were written with the subconscious realization that enforcement is difficult and expensive, and that the discretion of that enforcement is part of the power of the government. Blindly translating those centuries of laws into rigid, free enforcement is a terrible idea for everyone. Yet we still have almost no recognition that that is an issue. This could, perhaps surprisingly, be one of the first places we directly grapple with this in a legal case someday soon, that the legality of something may be at least partially influenced by the expense of the operation. We should welcome more precise law enforcement. Imperfect enforcement is too easy for law enforcement officers to turn into selective enforcement. By choosing who to go after, law enforcement gets the unearned power to change the law however they want, enforcing unwritten rules of their choosing. Having law enforcement make the laws is bad. The big caveat, though, is that when enforcement becomes more accurate, the rules and penalties need to change. As you point out, a rigidly enforced law is very different from one that is less rigorously enforced. You are right that there is very little recognition of this. The law is difficult to change by design, but it may soon have to change faster than it has in the past, and it's not clear how or if that can happen. Historically, it seems like the only way rapid governmental change happens is by violent revolution, and I would rather not live in a time of violent revolution... The problem with precise law enforcement is that the legal system is incredibly complex. There's a tagline that ‘everybody's a criminal’; I don't know if that's necessarily true but I do definitely believe that a large number of ‘innocent’ people are criminals (by the letter of the law) without their knowledge. Because we usually only bother to prosecute crimes if some obvious harm has been done this doesn't cause a lot of damage in practice (though it can be abused), but if you start enforcing the letter of every law precisely it suddenly becomes the obligation of every citizen to know every law — in a de facto way, rather than just the de jure way we currently have as a consequence of ‘ignorance of the law is no excuse’. So an increase of precision in law enforcement must be preceded by a drastic simplification of the law itself — not a bad thing by any means, but also not an easy (or, perhaps, possible) task. The reason speed limits make such a great example for these arguments is because they're a preemptive law. Technically, nobody is directly harmed by speeding. We outlaw speeding on the belief that it statistically leads to and/or is correlated with other harms. Contrast this to a law against assault or theft: in those kinds of cases, the law makes the direct harm itself illegal. Increasing the precision of enforcement makes a lot more sense for direct-harm laws. You won't find anyone seriously arguing that full 100% enforcement of murder laws is a bad idea. It's the preemptive laws, which were often lazily enforced, especially when no real harm resulted from the action, where this all gets complicated. Maybe this is the distinction to focus on. This unwritten distinction exists only to allow targeted enforcement in service of harassment and oppression. There is no upside (even if getting away with speeding feels good). We should strive to enforce all laws 100% of the time as that is the only fair option. If a law being enforced 100% of the time causes problems then rethink the law (i.e. raise the speed limit, or design the road slower). > If a law being enforced 100% of the time causes problems then rethink the law (i.e. raise the speed limit, or design the road slower). Isn't this the point of the whole conversation we are having here? Laws on copyright were not created for current AI usage on open source project replication. They need to change, because if they are perfectly enforced by the letter, they result in actions that are clearly against the intent of the law itself. The underlying problem is that the world changes too fast for the laws so be fair immediately What would really help is for people to understand that that's the "spirit of the law" and the "letter of the law". People don't want the letter of the law enforced, they want the spirit. Using the example from above, speed limits were made for safety. They were set at a time and surprise, cars got safer. So people feel safer driving faster. They're breaking the letter of the law but not the spirit. I actually like to use law as an example of the limitations of natural languages. Because legalese is an attempt to formalize natural language, yet everyone seems to understand how hard it is to write good rules and how easy it is to find loopholes. But those are only possible if you enforce the letter of the law. Loopholes still exist but are much harder to circumvent with the spirit of the law. But it's also more ambiguous, so not without faults. You have to use some balance. >cars have gotten safer For their inhabitants, maybe not pedestrians though. Speeding laws are in part for protecting pedestrians In general cars have also gotten safer for pedestrians[0]. Modern cars are lighter and made of plastic. There's better visibility, sensors, and for most vehicles the shape of the car has improved things. American trucks are an interesting counter example but that's a more complicated issue. (The source has a comment that you can infer this being a concern with trucks but there's also a lot of sources on this that you can easily find) [0] https://www.fox7austin.com/news/data-40-year-high-auto-ped-d... ^This. A large % of jurisprudence is in just trying to keep up with how tech disrupts society. The reason that has to be done is precisely that the law has no common, well-architected rationale. The vast majority of law in common-law jurisdictions is ad hoc precedent from decades or centuries ago, patchwork laws that match current, ephemeral intuition about what the law should be, etc. Perfect and inevitable enforcement makes this situation a nightmare, given the expectation that the average US citizen commits multiple felonies per day. Something will have to give. The speed limit example is a great one. Consider a road that has a 35mph limit. Now - which of the following scenarios is SAFER:
a) I'm driving on the road in a brand new 4x4 porsche on a sunny day with great visibility and brand new tyres. Doing 40mph.
b) I'm driving on the same road in a 70s car with legal but somewhat worn out tyres, in the dark, while it's raining heavily. Doing 35mph. Of course technically option a is violating the law but no sane police officer will give you a fine in this case. Nor should they! A robot will, however. This is stupid. The Cayenne would be safer going 35 instead of 40 regardless of all other variables. It's a trivial physics question, kinetic energy is a function of mass and velocity. The Cayenne would not be safer going 35 instead of 40 "regardless of all other variables": it's statistically safer to go closer to the flow of traffic because you're then "at rest" with respect to other drivers (assuming a controlled access road without pedestrian traffic). If the speed limit is 55 and the flow of traffic is 70–80 (as is the case with the Beltway around DC, despite automated enforcement), then going 55 is more dangerous than "speeding". The issue with 100% enforcement is every law assumes certain circumstances or variables and the real world is infinitely more complex than any set of variables that can reasonably be foreseen by law (and laws that attempt to foresee as many variables as possible are more complicated and, consequently, harder for normal people to apply, which is another reason for latitude in enforcement). The problem with your DC beltway example wouldn’t be automated enforcement then, but with the speed limit itself. A road without pedestrians and intersections in it should have a speed limit that reflects the reality of its use (70-80) safer for whom? Remember cars are not the only ones participating in traffic.
