2017 has seen a resurgence in the U.S. Border Patrol’s ongoing war against freedom of movement inside the country. This despite the fact the U.S. Border Patrol is supposed to, well, patrol the actual border:
The United States Border Patrol (USBP) is an American federal law enforcement agency. Its mission is to detect and prevent illegal aliens, terrorists and terrorist weapons from entering the United States, and prevent illegal trafficking of people and contraband. It is the mobile, uniformed law enforcement arm of U.S. Customs and Border Protection (CBP), a component of the U.S. Department of Homeland Security (DHS). With over 21,000 agents, the U.S. Border Patrol is one of the largest law enforcement agencies in the United States. - Wikipedia
Given however that Customs & Border Protection has little interest in shutting down more than about 30% of illegal traffic at the actual border due to CBP corruption and the impact of enforcement operations on cross-border commercial traffic, one can see why the Border Patrol continues to shift its dog and pony show away from actual border enforcement activities and towards interior enforcement operations that significantly interfere with domestic traffic.
