On this edition of Your Call, journalist Ioan Grillo discusses his new book,Blood Gun Money: How America Arms Gangs and Cartels. Grillo has spent nearly two decades covering the drug war in Mexico. In his book, he exposes how the US fuels Mexico’s gun market. Every year, more than 200,000 firearms are estimated to be trafficked from the US to Mexico. The US House recently passed two bills to require background checks on firearms sales and transfers and to expand a 10-day review for gun purchases. Will the Senate finally take on the powerful gun lobby?
