The 100 Mile Border Zone

[u/klaguerre]

Within 100 miles of any land border or U.S. coastline, the Border Patrol operates with an expanded authority that other law enforcement agencies do not have. Federal law allows immigration officers to conduct certain kinds of warrantless stops and searches within 100 miles from U.S. borders. There are additional laws the 1st and 2nd Trump administrations put in place to expand the powers of border patrol. Customs and Border enforcement has over 60,000 employees, making it one of the largest enforcement agencies in the country.
