Can any FR detectives place him in the same city as the Dallas shooter during the same time period?
Were they both in the Texas National of Islam at the same time?
He was in Houston July 12 according to one of the videos in Daily Caller article—

At the beginning of the below video (uploaded July 10; the Dallas shooting was July 7), Long talks about being in Dallas. The way Long talks at the beginning of the video, he arrived in Dallas shortly after the Dallas shooting. Long insists that he had already planned in being in Dallas prior to the shootings.
Of course, this information is helpful only if you can believe what Long says.
