Activists are protesting Chicago’s curfew, saying exemptions for events like Lollapalooza are unfair.

CHICAGO (CBS) — FROM Lollapalooza in full swing, city against the curfew causes controversy.

The music festival in Grant Park brings together young people. But as it stands, the 10pm curfew for those under 18 does not apply during certain events, including ticketed concerts.

As CBS 2 host Maribel Gonzalez reported Friday night, some youth activists say it’s unfair that the curfew applies to some teens and not others.

They say in the city that the curfew is a way to suppress crime. But activists call it unconstitutional and say they are ready to go to court.

They used Lollapalooza itself as a platform to protest against the city’s policies.

“If you have a Lollapalooza ticket – general admission or not – then you don’t have to respect this curfew, which immediately struck me as really strange,” said youth activist Isaiah Pinzino of Brighton Park Borough Council.

On the opening day of Lollapalooza, Pinzino, along with other GoodKids MadCity activists, stood at the gates of the concert, denouncing the city’s 10:00 pm curfew, as well as a decree prohibiting unaccompanied minors Millennium Park on weekend nights.

A clause in the ordinance allows minors arriving from a ticketed event such as Lollapalooza to leave after curfew.

“It also shows that they are willing to sidestep the supposed security reforms they are introducing for concert goers – which is absolutely ridiculous,” Pinzino said.

Back in May, Mayor Lori Lightfoot announced the measure as a way to combat crime, shootings and rowdy crowds. It is known that a 16-year-old boy named Sandell Holliday was shot dead in front of the Cloud Gate sculpture during the Millennium Park riots in May.

But activists say curfews and other restrictions on youth are not the answer.

A lawyer representing the activists sent a letter to the city asking them to lift the curfew. They call the measure unconstitutional and disproportionately affecting black and brown teenagers.

The city did not respond to our request for comment on the letter.

We also contacted the Chicago Police to find out what happens to teenagers who attend a concert and stay after curfew. City officials said, “It is a protection for a minor to participate in or return from a ticketed event.”
