“Do you feel guilty?” – Watch the BBC correspondent challenging the BBC correspondent, which follows the trade of deadly drugs

President Donald Trump sees his commercial war as a way to pressure Mexico to do more to stop the flow of illegal drugs to the United States.

The BBC Cointeen Summerille correspondent traveled to the borders of the United States of Mexico and followed Fintanel's smugglers – before talking to the addicts in Philadelphia.

Watch while meeting with some drug agents and challenging them on the deaths caused by their pills.
