Here is a good example of why police can't be trusted to enforce themselves. They fight transparency, the key issue here, at every chance.
http://reason.com/...-unions-endanger-min Conservative police apologists often dismiss this frustration, claiming that police shootings are the result not of bigotry and bias by police but greater black crime rates. And to prove their point they have seized on a study by Harvard University's Roland G. Fryer, black himself, that found no evidence that police are more likely to use lethal force against blacks and Hispanics than whites. (However, the cops are 50 percent more likely to use non-lethal force such as slapping, slamming, and punching against blacks and Hispanics than whites and Asians.)
But Fryer, a careful researcher with a stellar reputation,
doesn't have great confidence in his own findings because comprehensive national data about police shootings doesn't exist. His investigation was therefore limited to select areas of Texas, Florida, and Los Angeles that were willing to share their internal records. And this, he acknowledges, introduced a massive self-selection bias in his sample. "
These departments only supplied the data because they are either enlightened or were not concerned about what the analysis would reveal," he noted. So why don't national stats exist? Because America's 18,000 law enforcement agencies don't want them to. The Crime Control Act of 1994 asked the FBI to annually compile and publish data about the use of police force in all instances so that the country could keep track of trends of police violence, identify problematic precincts, or catch enforcement bias. But
union representatives of law enforcement agencies successfully lobbied the feds to make reporting optional. So most departments now simply plead poverty and refuse to comply.
This is a huge problem. In the absence of good data, it is impossible to say definitively if racism is driving police abuse in black communities. And because it is impossible to identify the size and scope of this problem, it is impossible to craft and enact a solution to it—a solution, mind you, that would not only better serve and protect minority communities, but also keep police safer, too.
"In the world I see you are stalking elk through the damp canyon forests around the ruins of Rockefeller Center. You'll wear leather clothes that will last you the rest of your life. You'll climb the wrist-thick kudzu vines that wrap the Sears Towers. And when you look down, you'll see tiny figures pounding corn, laying stripes of venison on the empty car pool lane of some abandoned superhighway." T Durden
