Random sampling over time is substantially as effective as having someone enforce the law 100% of the time. It's something like how randomized algorithms can be faster than their purely-deterministic counterparts, or how sampling a population is quite effective at finding population statistics.
It feels less fair though. When everyone is driving x mph over the limit but only you get pulled over, it sucks. So I agree for efficiency of enforcement, but I'd rather see 100% enforcement (automated if possible), with more warnings and lower penalties.
It's only unfair if the innocent are punished. Lot of murders go unsolved. Does that mean the murderers that do get caught are treated unfairly?
That's a pretty extreme example, maybe the idea doesn't hold as much there. But yeah, if 99% of murders weren't prosecuted, the 1% who get charged might feel like they were singled out (and maybe they were, because of some bias or discrimination). Again, 100% enforcement is better.
It doesn't just "feel" less fair, it often is -- bc it's not truly random, it's selective enforcement which leads to things like "driving while black".
The problem with 100% enforcement is it doesn't allow law enforcement any discretion, and then you end up having to actually officially change the speed limit which would probably never happen
Definitely true in practice, but I don't think we want discretion. What I mean though is as a deterrent, you can either have a "fair" fine that's enforced 100% of the time, or 2x the "fair" amount with 50% enforcement, etc. When it's 100x the "fair" amount with 1% enforcement, and you see everyone else not being enforced, it feels unfair.
