If one takes as a given that traffic laws are normally enforced in a discriminatory manner by humans, then one might infer that minorities drive more carefully than the average citizen as a result, (incentives!) and therefore when we see a disparity such as with traffic cameras, there must be significant racial bias even if it is not obvious and it is supposed to be "objective." Whether it be camera placement, algorithms, or something else. Does that make sense? When you know the answer to something in advance, you don't throw away your facts based on a chain of logical reasoning, you look for the flaw in the reasoning. After reading the article, they have lots of information on where the disparities are arising. The wide streets where the city speed limit seems excessively low tend to predominate in the ticketing. I haven't lived in a city with widespread speed cameras, but I know the type of street exactly. In fact, it's been my opinion for a long time that a certain stretch of highway going out of my city is marked for 30 mph to ensure that police always have probable cause to stop anyone no matter what. Just a little further it's posted for 45 mph, and people go 55+. Anyone who goes at the speed of traffic in the 30 zone can be stopped for speeding, and anyone who goes the speed limit can be stopped for obstructing traffic and probable intoxication. But at least there aren't automated cameras.
