Up to 4,000 bikers are expected to ride through Waco, Texas, in protest Sunday at an “All for 1” rally following the violent shootout between the Bandidos and Cossacks motorcycle clubs that left nine dead and 18 injured on May 17. More than 100 bikers who were arrested last month at Twin Peaks restaurant reportedly remain behind bars in the McLennan County Jail.

Organizers, who have called the event a peaceful, silent protest, will gather in front of the McLennan County Courthouse to protest what they say is the violation of rights of many bikers who were arrested at Twin Peaks just for being at the scene of the crime. “Not everyone that rides a motorcycle is a bad person,” John Rozean, an independent biker, told KWTX-TV Waco. “There were people that were riding that did commit a crime, but it’s hard to say that everyone in that area was responsible.”

Bikers planned to kick off the ride at 8 a.m. CDT at Sam’s Club on East Waco Drive, then ride through Waco. Groups are preparing to hit the road this morning, but a few were disappointed by the turn out as only 50 motorcycles arrived at Sam’s Club, the Waco Tribune reported. The group will hold lunch at the McLennan County Courthouse at 12:30 p.m. CDT.

Law enforcement officials said they welcome the bikers as long as everything remains calm. “We don’t have an issue with that. That’s what America is about. Freedom of speech and freedom to assemble,” Patrick Swanton, Waco Police Department, told KWTX-TV Waco. “The key there is to do it peacefully.”

Following the shootout last month, 170 bikers were arrested on first-degree felony charges of engaging in organized criminal activity. Waco police said the more than 300 weapons found at the scene show there was “criminal intent” among those who were jailed in the immediate aftermath of the shooting, even if they weren't directly involved.
