CHICAGO (CBS) — An unusual sight at Daley Plaza in Chicago during the lunch hour Friday as 170 men and women stood in silence in front of the 50-foot Picasso. WBBM’s Lisa Fielding reports.

“This is Rape Victim Advocates’ signature event. We are standing silently for one hour together to show the stigma and silence that typically surrounds the issue of sexual assault,” said Megan Blomquist, Director of Education & Training, Rape Victims Advocates.

Many were wearing t-shirts with powerful statements about sexual assault.

“If you take a look around, a lot of the t-shirts are hand made by sexual assault survivors, loved ones and supports with messages on them,” Blomquist said.

“Get consent! Get consent,” the group chanted. “What do we want? End rape culture. When do we want it? Now!”

Blomquist said the annual event is a symbol of education, awareness and progress.

“I think there’s been progress, but that’s always difficult to say however, what we have seen is that more people are talking about it, more people are volunteering for groups like ours. We are making progress but there’s a long way to go,” she said. “Having events like this, having demonstrations, having conversations about sexual violence certainly help eliminate some of that stigma and allow more people to come forward without that sigma and feeling ashamed.”

“Intoxicated consent is not consent.” (WBBM/Lisa Fielding)
