William R. Brownfield: “This opioid crisis is perhaps our worst drug crisis in 30 years.”

Heroin is now found in neighborhoods, cities, regions of the country where it never was seen before.

If you take ivory completely out of any commercial value whatsoever, you have the impact of discouraging the criminal networks from continuing to poach.

The overwhelming majority of the heroin that is now entering the United States is coming from Mexico.

I do believe that the federal Government of Mexico today has far better, more professional, better trained and equipped institutions than they did at the start of the Merida Initiative 7 or 8 years ago.
