“Federal law enforcement officials told NBC News the suspected gunman had no obvious connection to domestic terror or white supremacist groups and apparently was not on any list of suspected terrorists. The suspect was in his early 40s, and while he had an arrest record, it was for minor traffic offenses, a federal official said, NBC reported. “
This is from the India Times so why are the news outlet's here saying he is a skinhead when this one says he is not and has not connection to domestic terror. I also thought it was interesting that the only run in with the law he had was a traffic violation same as the Batman Killer.
