This is discussed towards the end of Section 2, where he attempts to establish that the set of inmates charged with violent offenses is mostly disjoint with the set of inmates charged with drug offenses.
Thanks for the pointer. Are you referring to Sections II C&D? Tables 4A and 4B seem like they would have the same categorization issue I described above. As I read it, the "Never drugs" column refers to a given offender never having a drug offense as the most serious offense for a conviction. This doesn't mean that the offender was never charged with a drug offense.
