Bruce Springsteen just went full scorched earth on the Trump administration’s immigration crackdown, calling ICE’s tactics in Minneapolis “Gestapo tactics” and declaring that America’s founding values “have never been as endangered as they are right now.”

The Boss didn’t mince words during a Saturday concert in his home state of New Jersey, where he dedicated his 1978 song “The Promised Land” to Renee Good, the 37-year-old mother of three who was shot and killed by an ICE officer in Minnesota.

WHAT HE SAID: “If you believe in democracy, in liberty, if you believe truth still matters, and it’s worth speaking out, and it’s worth fighting for; if you believe in the power of the law and that no-one stands above it; if you stand against heavily armed masked federal troops invading an American city, using Gestapo tactics against our fellow citizens; if you believe you don’t deserve to be murdered for exercising your American right to protest, then send a message to this president.”

Then came the kicker, quoting Minneapolis’s mayor directly: “ICE should get the fuck out of Minneapolis.” The crowd roared.

THE BACKSTORY: This isn’t Springsteen’s first rodeo when it comes to calling out Trump. The musician—whose entire catalog is basically a love letter to working-class Americans getting crushed by the system—has been sounding the alarm for years.

At a show in the UK last May, he laid out the case plainly: “In my country, they’re taking sadistic pleasure in the pain they inflict on loyal American workers. They’re rolling back historic civil rights legislation that led to a more just and plural society. They are abandoning our great allies and siding with dictators against those struggling for their freedom.”

OF COURSE: Trump responded exactly how you’d expect—by attacking Springsteen personally. The Rock & Roll Hall of Fame member is “highly overrated,” Trump said, calling him “not a talented guy” and a “pushy, obnoxious jerk.”

Yes, the guy with 20 Grammy Awards and album sales in the hundreds of millions is “not talented.” Sure.

WHY IT MATTERS: Springsteen dedicating a song to Renee Good isn’t just celebrity activism—it’s forcing a spotlight onto a killing that the administration would prefer you forget about. An American citizen, a mother of three, shot dead by federal agents. That’s not immigration enforcement. That’s state violence.

When one of America’s most iconic voices uses his platform to invoke the Gestapo comparison, it’s worth paying attention. The comparison isn’t hyperbole when masked federal troops are flooding American cities and citizens are dying in the streets.

As Springsteen put it, the song was about “both the beautiful but flawed country that we are, and to the country that we could be.” Right now, the gap between those two things is getting harder to ignore.
