Excellent points. Prompted by this discussion I read a recent New Yorker article on developments at the Border Patrol and Department of Homeland Security, including the appointment of anti-immigration ideologues to the DHS. On the matter of discipline (among other things), the article is hardly encouraging:

<<Donald Trump has long been signalling to agents that he’s on their side. “When President Trump says that he’s going to let law-enforcement agents ‘do their job,’ it’s insidious code,” Chris Rickerd, a lawyer with the American Civil Liberties Union who specializes in the C.B.P., told me. As Brandon Judd, the head of the Border Patrol Council, told an interviewer last summer, “I’ve seen the lawlessness on the border . . . and [Trump] has seen how that affects the morale of the Border Patrol not being able to do your job. . . . He wants to take those handcuffs off.”>>
