I don't have a direct link, sorry. Randy Balko posts a lot on such topics on his blog The Agitator. I don't agree with all of his politics, but he links to a variety of sources, and seems generally credible. I haven't read his writings so much since he signed on at the Huffington Post. His old blog at TheAgitator.Com is still up, though all postings are at the new blog. I think the new blog has archives of the old one, but I haven't tried searching them.
In other words, what you stated as fact, isn't. Randy Balko the cop hater?

Not surprising that a avowed cop hater would leave out facts that would prove him wrong. How could he justify his allegations if he did that? Balko being a loony tune doesn't bother me so much, since there are plenty of them to go around, but the fact that Instapundit would link to him twice so far is sad.
