Radley Balko: "Of 146 no-knock raids conducted [in Denver in 1999], only 49 produced charges of any kind. And of those, just two resulted in prison time for the targets of the raids. In comparison, the paper noted that while 21 percent of the city's felony defendants on average are sent to prison, just 4 percent of its no-knock defendants were. One former prosecutor said of the results, 'When you have that violent intrusion on people's homes with so little results, you have to ask why.'" Explaining why is easy; doing it without a profusion of four-letter words is not.
