However, Border Patrol suffers from worse discipline, performance, and corruption problems than any other federal law enforcement agency, my study for the Cato Institute found. Congress disbanded the old Immigration and Naturalization Service that housed Border Patrol after it approved student visas for two 9/11 hijackers about six months after they flew jet liners into the World Trade Center. Furthermore, the Government Accountability Office should annually audit Border Patrol internal affairs through undercover investigations to catch agents breaking the law or otherwise misbehaving. Also, in the interest of transparency, the government should annually publish all corruption and misconduct information for every federal agency so that Border Patrol’s track record can be compared with others, which is extremely difficult right now. Congress should not authorize any additional hires until Border Patrol gets a grip and improves its personnel record to at least the level of other federal law enforcement agencies, which is hardly a high bar.
