The libertarian publication Reason revealed a 2012 internal affairs report indicating that a CBP instructor had told “a room full of supervisors” that “if Border Patrol agents feel threatened by a migrant, they should ‘beat that tonk like a piñata until candy comes out.’” The word “tonk” or “tonc” is reportedly Border Patrol slang for an undocumented migrant. Former agents say that the word originates from the sound a human skull makes when clubbed with an agent’s heavy Maglite flashlight.
