Overall, the researchers believe that “the police beating of Frank Jude resulted in a net loss of approximately 22,200 911 calls reporting crime the year after Jude’s story broke,” and that’s during a span in which there were about 110,000 911 calls to the police total. And while black people are 40 percent of the population in Milwaukee, “Over half (56 percent) of the total loss in calls occurred in black neighborhoods.” There was no such drop for calls reporting automobile accidents, further supporting the researchers’ theory that the effect had to do specifically with crime reports. Eventually the overall number of calls returned to where it was “supposed” to be.None of this should be a surprise to anyone. If you think that the cops are acting as an occupying army in your neighborhood, you're not going to call them.
The referenced beating was yet another case where the local prosecutors dragged their feet and, when they eventually brought the eight cops involved to trial, all were acquitted by (wait for it) all-white juries.
The Bush Administration DoJ had better luck. Four pleaded guilty, receiving sentences of between 12 to 32 months. at trial, one cop got off, the others were found guilty and sentenced to between 15 and 17 years in prison. All appealed and one got to be resentenced (and was resentenced to the same term).
