Protestors gathered around Houston City Hall a day after a jury found George Zimmerman not guilty of second degree murder and declined to convict him of manslaughter in connection with the death of Trayvon Martin.
As they vented frustration, Houston police stood nearby.
"They must be on Facebook too," said Nell Douglas. Douglas said she found out about the protest, which was organized by Occupy Houston, on the website.
"We used social media and we got word out very quick," said Shere Dore, with Occupy Houston.
Zimmerman's acquittal was a hot topic on social media sites like Twitter, and in area churches, where some pastors voiced concern and disapproval, but urged parishioners to trust in God and refrain from violence.
"What I am concerned about is what appears to me is that justice took a reprieve upon last night," said Pastor Timothy Sloan of St. Luke's Baptist Church in Humble.
The details of Martin's death and Zimmerman's arrest created a racially charged case that sparked nationwide interest. Earlier this year Fox 26's Isiah Carey obtained an exclusive interview with Robbie Tolan.
Back in 2008 Tolan, the son of a major league baseball player and a rising prospect himself, was shot in his parent's front yard by a Bellaire police office. His attorneys said he was a victim of racial profiling.
A jury eventually decided the officer was not guilty of aggravated assault.
"I lived in a very affluent neighborhood," Tolan said in February. " I was from a certain background. And I said it's unfortunate and its tragic, but that probably won't happen to me. And it did. It was an eye opener."
Tolan's story, along with Martin's, were featured in an episode of "The Injustice Files" on Investigation Discovery Channel earlier this year. The episode's producer said it was meant to call attention to racial profiling. Tolan did not return our phone calls Sunday, but others are talking.
"Now you can say all you want that it's not about race," Sloan said to his congregation. "You can get in front of the cameras and you can talk and say this has never been an issue about race, but that's a lie."
