The Drug Enforcement Administration is raiding pain clinics, pharmacies and other locations in four southern states as part of a crackdown on prescription pain drug abuse. A federal law enforcement official says the raids in Arkansas, Alabama, Louisiana and Mississippi are the final stages of a nearly yearlong operation by the D-E-A's drug diversion unit. This video is from Little Rock, Arkansas. Since last July about 140 people have been arrested, and agents expect as many as 170 more today. The official says suspects in the D-E-A's "Operation Pilluted" include doctors and pharmacists. The investigation is focusing on the illegal sale of opioid pain killers, including oxycodone and hydrocodone.
