In efforts to disrupt ICE, the whistle has become an instrument of choice
On the streets, the whistle has become a means to alert neighbors and warn immigrants.
The eastern sky is aglow with dawn streaks of orange when the cry of a whistle sounds outside of ICE headquarters in Philadelphia.
The noise pierces amid an improvised orchestra of protest, as chanting demonstrators shake tambourines, rattle jingle sticks, and beat drums ― one person banged on a kitchen colander ― to create a clamor that makes it challenging to concentrate.
That’s part of the goal of the weekly “Noise Demo” organized by No ICE Philly to raise awareness among morning commuters but also to try to disrupt the work of Immigration and Customs Enforcement agents at the Eighth and Cherry Street office.
“We’re interrupting them,” said a protest leader who asked to be identified only as a member of No ICE Philly out of fear of repercussion from the government.
For advocacy groups here and across the county, the whistle has become both a tool and symbol of the anti-ICE movement.
On the streets, it’s the means to alert neighbors and warn immigrants when ICE arrives on the block, and to try to distract and confuse officers who may already be operating in an unfamiliar neighborhood.
A blast from a standard pea whistle can carry half a mile, and the sound from a specialized emergency whistle can travel a mile or more, depending on conditions.
ICE officials in Philadelphia said last week they had nothing to add on the noise demonstrations or on the use of whistles, beyond what the agency had already said: “Your whistles won’t stop or hinder ICE from arresting criminal illegal alien sex abusers, murderers, gang members, and more,” the agency told Minnesota protesters on social media.
In November, President Donald Trump issued a ban ― so far blocked by the courts ― on creating “loud or unusual noises” at federal facilities in the U.S. That hasn’t slowed No ICE Philly, which gathers to make noise on Mondays, though the snowfall pushed a recent action to Thursday.
“Maybe,” said activist Huston West, who blasted a steady beat on his whistle as ICE officers arrived at work on Thursday, “it makes them think about their life choices.”
Why have whistles become so popular among immigration protesters?
Many reasons.
Whistles are light, portable, reliable ― and cheap, about 20 cents each when bought in bulk. They don’t need batteries or recharging, have no buttons or controls. Everyone knows how to make it work.
“There’s not much more shrill or penetrating than the sound of a whistle,” said Temple University professor Ralph Young, who studies protest and dissent.
To him, protesters’ use of whistles carries symbolism, summoning images of referees calling penalties during sports events. Maybe the activists are saying ICE has broken the rules or needs to stop.
“Like throwing a penalty flag,” he said, “against ICE agents who they deem are acting unlawfully.”
The whistle ranks among the oldest human inventions, the first ones crafted from bone, wood, or clay, used for hunting, signaling, and religious rites.
Englishman Joseph Hudson is considered the inventor of the modern pea whistle ― the tiny ball in the air chamber produces the trill ― in the 1880s. He created the Metropolitan Police whistle for British bobbies and the Acme Thunderer for soccer referees, who to that point had waved handkerchiefs to signal fouls.
Today, hundreds of thousands of whistles have been distributed to ICE protesters around the country ― more than 150,000 sent from Chicago alone, according to the Chicago Sun-Times.
In Minneapolis, activists have used 3D printers to crank out supplies. In Philadelphia, whistles have been given out by the handful at organizing meetings. Temple Beth Zion-Beth Israel ordered 300 whistles for distribution, so neighbors can quickly signal that ICE is present and warn immigrants to seek safety.
“The big orange ones are the best,” Rachel Monk wrote in the Progressive, in an essay that proclaimed 2025 the Year of the Whistle. “I don’t leave my apartment without mine.”
In Maryland last month, the Washington County commissioners shut down a public meeting when protesters blew whistles to condemn the board’s support for turning a warehouse into an immigration detention facility, the Baltimore Banner reported. And in Arizona, a state senator introduced a bill to outlaw the use of whistles to warn neighbors of ICE, seeking to create a new state crime called “unlawful alerting.”
The Trump administration wants to ban loud noises outside federal facilities, a move widely seen as an effort to halt protests at ICE offices. A federal judge in Oregon temporarily blocked the restrictions, saying they said could violate the First Amendment by criminalizing free speech.
But even among pro-immigration activists, not everyone sees whistles as consistently beneficial.
Some think the noise adds to the confusion at the scenes of ICE arrests, increasing fear and anxiety among families during what are already tense and sometimes violent encounters.
New Sanctuary Movement of Philadelphia, a major advocacy organization, has begun talking to other groups about finding alternatives to whistles, said co-director Blanca Pacheco.
Yes, she said, it’s important that arrests not be permitted to be carried out in silence. But “what is the kind of noise that people can come up with that is supportive, instead of adding to the trauma?”
Not all in immigrant communities understand the purpose of the whistles, she said. And for those who have survived war or torture the noise can be triggering.
One option may be that people could shout, “ICE is here!” Perhaps two or three people on a block could be designated to blow whistles, rather than everyone at once. Even singing could work, she said.
“I think that Chicago and Minnesota and other places that have used the whistles had to come up with tactics and strategy very quickly,” said Pacheco, who noted Philadelphia is not in that position. “We can learn from other places what has worked and what has not. I think whistles can be used in some scenarios, not all the scenarios.”
Outside the ICE office on Thursday, two ICE agents heading into the building jawed with demonstrators who yelled at them to quit their jobs. Whistle calls and drum beats continued on, toward an 8 a.m. conclusion.
“ICE operates from the very early morning into early afternoon,” said the demonstration leader who declined to give his name. “We just want to make sure that we’re here when they’re here.”
