Dallas sniper reportedly planned larger attack, changed plans to target protest

The Army says Micah Xavier Johnson, named as a suspect in the Dallas police shootings, served in the Army Reserve for six years and did a nine-month tour of duty in Afghanistan.
FOX NEWS - Investigators believe the Dallas gunman who shot 14 people, including five murdered police officers, originally planned a much larger attack.
Dallas' WFAA-TV, citing a law enforcement source with knowledge of the investigation, reported that authorities think Micah Johnson changed his attack plan so the shootings would coincide with Thursday's protest against police brutality.
"We think he was probably planning something bigger based on what we found at [Johnson's] house [in suburban Mesquite]", the source said "He had a bunch of explosive materials. He didn’t have the explosives created."
Among those materials were metal pipes, as well as chemicals that could be used to create pipe bombs. It was not immediately clear whether Johnson had any specific targets in mind for a larger attack.
The source added that Johnson "literally had hundreds and hundreds of rounds in magazines attached to his body [Thursday] so it wasn’t like he was running out of ammunition ... His plan was to kill as many as he could."
