Attorney General Eric Holder testifies on Capitol Hill in Washington, Thursday, April 3, 2014, before a Senate Appropriations subcommittee on proposed budget estimates for fiscal year 2015 for the Justice Department. Holder said the government needs to deal differently with the heroin epidemic than it did with the crack cocaine crisis decades ago. Holder told the subcommittee that a "balanced approach" involving treatment, education and enforcement is needed to confront the country's heroin crisis and avoid mistakes made during the widespread use of crack. Police at that time focused on large-scale arrests and imprisonment. (AP Photo/J. Scott Applewhite)
