I think more statistics would be crucial to making this point about Sporadic Enforcement, whichever way it goes. The simple Risk calculation of Punishment*Likelihood isn't very informative. Most people aren't great at math, and even if they are it isn't all that influential. Sporadic Enforcement plus Heart Stopping fines seems to be the strategy used by the RIAA, and the consensus is that it is totally ineffective. Perhaps even counterproductive, as it turns public sentiment against them. I realize that traffic fines are much less sporadic than that, and that high fines give the Police incentive to increase enforcement, but I'm not prepared to assume, based on logic and an anecdote, that the strategy "works". Most data and metrics are subject to the criticism below, but it would give you some basis to begin your comparison. - Stephen Severo
