It was true for Dylann Roof in Charleston. It was true about for any number of violent white men in Charlottesville. And it was true for Nikolas Cruz in Parkland, Florida.
Like these other young men who turned violent, lots of people who interacted with Cruz saw the day coming when he would do something drastic, maybe even one day shoot up a school.
He had long since been expelled from his high school. One student who had served with him in the Junior ROTC called him “a psycho.” Another student said he was a weapons enthusiast who tried to sell weapons at school. Yet another student said he had been banned from bringing a backpack to school as a student after bullet casings were found in it.
