When news broke last weekend that federal immigration agents had shot and killed a second U.S. citizen in Minneapolis, the Department of Homeland Security (DHS) was quick to go on the offensive. Miller is the White House aide who turns Trump's immigration ideas into reality. Under Miller's watch, immigration agents on the street aren't just duly enforcing immigration law, they are doing so in a way that engenders maximum conflict and maximum hostility, emphasizing shows of force over dispassionate legal procedure. That sense that enforcement has gone too far is a direct byproduct of the incendiary tactics Stephen Miller favors. But it's hard to make a persuasive case that masked, militarized law enforcement tactics are necessary to protect Americans when confronted with videos showing Americans losing their lives and their liberty to those very same tactics.
