A former U.S. Immigration and Customs Enforcement instructor responsible for educating new ICE officers on proper use of force told Congress Monday the agency's efforts to rapidly scale up its ranks will place recruits on the streets without the training they need to lawfully carry out immigration enforcement.

"New cadets are graduating from the Academy, despite widespread concerns among training staff that even in the final days of training, the cadets cannot demonstrate a solid grasp of the tactics or the law required to perform their jobs," Ryan Schwank said yesterday.

"Without reform, ICE will graduate thousands of new officers who do not know their constitutional duty, do not know the limits of their authority and who do not have the training to recognize an unlawful order. That should scare everyone," he warned

Schwank, an attorney and former career ICE employee who resigned less than two weeks ago, quit the agency in protest. It stands as one of the first instances of an ICE official publicly rebuking the agency and the adequacy of its training.
