Jaeson Jones is a former Texas DPS captain, border security strategist, and one of the country's leading experts on cartel operations. In Episode 67 of Going Rogue with Lara Logan, he sits down with Lara to explain what he witnessed firsthand while embedded with the Mexican Navy.

Lara presses him on the scale of the chemical flow coming into Mexico from Southeast Asia and China.

Jaeson asked a Mexican Navy captain how many precursor chemicals they monitor daily.

He expected maybe twenty.

The answer: seventy-one.

In just thirteen months, the Mexican Navy seized 800 tons of chemical precursors.
