"Y' all lookie here, I am Trayvon Martin, y'all better wake up!" said one woman.

For others, the march tapped into local tensions.
"There's a lot of ache, a lot of pain that's been going through the city of Tulsa," said Kavin Ross, putting the event in historical context.
"Greenwood residents suffered a lot back in '21, the Northern sector of Tulsa has been going through a lot, but this right her we ought to put our best foot forward and show that there needs to be some respect," he said.
It was a quiet march, no chanting, no bullhorns, but plenty of emotion just under the surface.
"Man, when I heard the verdict on Saturday I started crying immediately, I just started shedding tears," said Shalik Williams, echoing the message that what happened to Trayvon hits close to home.
"I have a 17 year-old nephew, it could have easily been them it could have easily been me when I was that age. It's senseless, it's sad, and crying I feel bad for them too but, something has got to change," he said.
