In a dramatic proposal that harks back to one of the most storied chapters in American penal history, President Donald Trump announced plans to convert Alcatraz Island back into a high-security federal prison.

The move, aimed at addressing what he describes as a rise in violent crime, has sparked fierce debate across political and public spheres.

Located in the chilly waters of San Francisco Bay, Alcatraz once symbolized the federal government’s hardline stance on crime. From 1934 to 1963, it held some of the country’s most notorious criminals, including gangster Al Capone and George “Machine Gun” Kelly. Its remoteness and isolation made it nearly escape-proof and psychologically daunting—a true prison of last resort.

Now, decades after being transformed into a major tourist attraction under the National Park Service, Trump wants to resurrect the island’s darker past.

“When we were a more serious Nation, in times past, we did not hesitate to lock up the most dangerous criminals, and keep them far away from anyone they could harm,” Trump said in a Truth Social post on Sunday. “That’s the way it’s supposed to be.”

According to Trump, the current justice system has become too lenient, and bringing Alcatraz back into service would serve as both a practical and symbolic solution to combatting extreme violence.

Critics have quickly pushed back on the idea. California State Senator Scott Wiener, a Democrat, strongly denounced the proposal, likening it to the creation of a “domestic gulag right in the middle of San Francisco Bay.” He and others argue that the suggestion reflects a regressive attitude toward incarceration and fails to address the root causes of crime.
