Last week, a 17-year-old Chicagoan named Keith Cozart was sentenced to 60 days in juvenile detention after violating parole. Both his offenses were gun crimes: the first came in 2011, when Cozart pointed a firearm at a police officer; the second came with a video posted online that showed Cozart handling a gun at a firing range.
Cozart is better known to many reading this column as the rapper Chief Keef. Last month, his debut album Finally Rich was issued by Interscope Records. It was an instant hit, selling close to 100,000 copies in its first month. The album is the most widely celebrated example to date of drill, a rap subgenre whose name and mood is taken from the retaliatory culture of Chicago's innercity gang wars.
