And that has agents who patrol along the border here, extremely worried. We learned that U.S. Customs and Border Protection's Offices of Border Patrol and Training and Development are inspecting the quality of agents' M4 carbines throughout Border Patrol sectors nationwide. But agents tell us, some of those M4s have not been replaced. And, we've learned, agents are required to share rifles amongst each other.
