Three 10-year-old girls - Alexi, Alyssa and Deven - on Tuesday asked the Colorado Springs City Council to start a Whistle Power program and give whistles to every kid in the city.
A whistle saved their lives, they said.
"We heard you were going to spend $300 million on downtown Colorado attractions and we thought you could spend some of that on whistles," Alexi said. "We want to use some of that money for safety precautions and cameras for neighborhoods."
The girls, who did not want to give their last names, told councilors about a horrific event two weeks ago when one of the 10-year-olds, Alyssa, and a 3-year-old girl were chased in their Briargate neighborhood by a stranger.
Alyssa was walking with the preschooler when she saw a man get out of a white van and come toward them. He gave chase.
"I was scared," she said. "I had heard of the white van and that a man followed a girl."
The 3-year-old had a whistle that her big sister gave to her for emergencies just two days earlier. Alyssa blew the whistle as hard as she could.
Alexi, Deven and other neighborhood children heard the whistle and ran toward the sound. All of them screaming, they scared the man away.
"We think if we did not have the whistle with us that day, I might not be here to tell you about this," Alyssa told the council.
Alexi said the girls gave whistles to all the neighborhood kids. But they think the city should sponsor a Whistle Power program - they made Whistle Power T-shirts and showed their whistles attached to stretch cords around their wrists.
The event shook them and now they are afraid to play outside alone, Alexi said. They sleep with their whistles.
"We want people to know what happened," she said.
