And here is what one of them looked like:
Oh, and I almost forgot. Here’s Brennan David in the Columbia Tribune with statistics:
Columbia’s SWAT team served 106 narcotics search warrants between Jan. 1, 2007, and May 11, 2010. The Tribune, through an open records request, received 99 of those search warrants; the others were considered closed records for various reasons.
Of the 99 SWAT narcotics search warrants granted by the Boone County Circuit Court to Columbia police, officers executed 43 percent of them within hours of being issued. Of those, 65 percent resulted in one felony arrest, and 18 percent resulted in misdemeanor arrests.
But the percentage of warrants producing a felony arrest dropped drastically to 37.5 percent when investigators waited one day before serving the search warrant. In those cases, 50 percent produced misdemeanor arrests.
Many thanks to Grant Watkins and Greg Young, our interns, for doing much of the raw data processing.
