Police suspect that the attack was indeed planned. Here are some other details that have emerged via CNN.
— At least 10 police officers were shot by snipers during the protests, Dallas police Chief David Brown said.— Police negotiated and exchanged gunfire with a suspect for hours at a parking garage in downtown Dallas. That suspect is dead, a law enforcement official told CNN. The official did not say how the suspect died.— “The suspect told our negotiators that the end is coming,” Brown said. The suspect at the garage also told negotiators more officers were going to get hurt, and that bombs had been planted all over downtown.— Police found no explosives during primary and secondary sweeps of the area, Dallas police Maj. Max Geron said Friday morning on Twitter.— Two of the shooters were snipers who fired “ambush-style” from an “elevated position.— Officers killed include one officer with DART, the Dallas Area Rapid Transit agency, which operates buses and commuter rail in the city and surrounding suburbs.
— Retired FBI Special Agent Steve Moore said an attack of that magnitude required advance work.— “This was an attack planned long before — waiting for an opportunity to go,” Moore said. “I think there was so much logistically, ammunition-wise. They may not have planned the location, they may not have planned the vantage point. But they had prepared for an attack before last night’s shooting is my guess.”
