If you are looking for data on misdemeanors, there is no well of information.
Sorry. My post was a bit snarky.
You seem to be trying to make a point, but I really can't figure out what it could be. I just responded to your little statistical sleight-of-hand with what I had hoped was a small bit of good-natured humor.
To be clear, every cop knows, and most criminology academics believe, that in any given population, a small group of people (let's call them criminals) are responsible for most serious crimes. So, if you deduct the criminals from a given population, the remaining population will have a relatively low crime rate, regardless of other factors. That's what you seemed to be doing with your peach-picker analogy -- artifically 'gaming' the numbers to get the figure that you wanted.
Anyway, there is an explanation for the high incarceration rates of illegal aliens in California state prisons and LA county jails, and it has nothing to do with tarring the 'peach pickers' or resorting to fantasies about 'racist cops'. Can you think of what it is?
