"The authors [of Freakonomics] attribute the 1990s drop in violent crime to the legalization of abortion (in combination with increased jailing and tougher gun laws). But anthopologist Grant McCracken has a still more novel hypothesis: the drop in crime, he argues, can be attributed to hip-hop. (After all, they coincided...)
Carrie McLaren adds: "Imagine how big the drop in crime would have been if only Tupac, Biggie Smalls, Jam Master Jay, et al. weren't gunned down."
Oh Grant, everyone knows that hip-hop causes crime... (Stay Free!)
