Well, the victimization surveys tell us that for every category of crime that matters, there are large disparities in base rates that (a) predate policing decisions and (b) recommend focusing on black neighborhoods, because that's where the crime is. The idea that higher arrest rates are a self-reinforcing statistical artifact has no support from the data. The notion that "crime is where you look for it" is specifically undercut by victimization surveys as well as by murder, a crime that is largely impossible to conceal from the state indefinitely. If the baseline disparities are already so high to begin with, there's hardly any variance left over to be explained by self-reinforcing patrol strategies.
Put another way, if you took the first-order strategy you'd come up with by looking at the body count, and then layered the most moustache-twirlingly racist jaywalking policy that you could think of on top of it, the two strategies wouldn't look that much different.
That's all before questioning why it is a bad thing for neighborhoods to be policed for misdemeanors. I lived in West Baltimore for years and I can assure you that my neighborhood was, if anything, chronically underpoliced.
- pooya13 8y agoSo now you have moved the goalpost to: >> There might be unfair feedback loops, but they would be effectively negligible. First of all, it is curious to me that you mention the 8x disparity in murder rate but don't mention that the violent crime survey disparity is less than 0.2x. Secondly, you just claim that the policing has nothing to do with people being arrested at different rates but do not offer any evidence. Here are the actual numbers if you really care about facts. The victimization rates are 20.5% whites vs 24.1% blacks. Less than 18% difference. On the other hand incarceration rates are 0.7% whites vs 4.5% blacks. That is more than 540% difference. This means the blacks are being arrested at about 32 times the rate at which they commit violent crimes. So your claim that: >> "we can check by looking at crime victimization surveys, which generally show the same patterns of racial disparities as arrest records" is not only ignorant and false. It is so far from the truth that it is laughable.
- lambdaphagy 8y agoI'd love to respond substantively to this post, and in particular to your figures, but hn has threatened to ban me for discussing this topic. I suppose each of us can only make of that what we will. Best wishes!
- pooya13 8y agoI would have personally liked to hear your response but I guess it is what it is. Best wishes to you as well!
