Feel free to post evidence the study was flawed but don't dismiss it because you don't like the result.
Yes, blacks do seem, on the surface, to get harsher sentencing, but only looking at the surface of sentence received and race of the convict does not tell the whole picture. You have to look at the rap sheet. If two people commit the same crime but one has a lot more convictions than the other, of course that one is going to get a longer sentence for the same crime. No mention in the article of that variable though. Coincidence?
So why are Asians underrepresented? If we have a bunch of white supremacist cops why don't we see more Asians than whites arrested? (proportionately speaking)
Why do you always insist on arguing for the one or two "facts" that you think prove your position while ignoring some extremely glaring and relevant ones?
For example, it's less likely a poor black will have the money for a private attorney, so he gets the court-appointed public defender. Meanwhile, Mr. White can afford an experienced defense attorney from a prestigious law firm with 4 partners and a dozen paralegals working the case.
Also, a clean cut white boy who "made a mistake" and is captain of the local sports team, gets good grades, and has the potential to learn from this and not do it again plays well for juries and judges. Not the same when a black kid from a broken home, living in a gang-run neighborhood and on his way to becoming a high school drop out. He might not get the same treatment unless there is something that changes and gives us hope things can be different in his life.
So, if you want to analyze something, maybe analyze all the factors that are affecting the outcome. Leaving those out which point to a different conclusion than what you want to prove is dishonest!
If you want to talk about controlling variables, how about that study only existing in it's own bubble? Video simulation, while good for practice and training, is not an accurate testing method. Facing a real person who reacts, moves, talks, yells, distracts while someone comes from another direction ..... those are real life variables that impact the stories we see. Trying to measure that in a controlled setting is not realistic.
