Attorney General Jeff Sessions has announced a new task force to control the output of manufacturers and distributors of opioid drugs.  A worthy idea says Polk Award-winning reporter Lenny Bernstein of the Washington Post, and a welcome shift from the passivity of the Obama administration. But the change maybe a little late, since the opioid market is shifting away from Vicodin and Oxy-contin to the more dangerous and harder to detect Fentanils.  Meanwhile the national death toll from opioid overdoses continues to climb.
