Penn says accounts from the rival gangs were surprisingly consistent - police involvement was much greater than had been reported. Conspiracy theories are still circulating that undercover officers may have instigated the confrontation.One of Penn's interviewees, who he says is cooperating with police, witnessed the first shot and says he still has not recognized that first shooter, out of all the mug shots Waco police have shown him. Any video that may have been taken at the meeting is in the hands of the police, Penn says.
"We began this story thinking it was about Texas gang culture," Penn says. "It turned out to be a story about the Waco justice system."
