The cyberverse offers ample opportunities for wackos to post thoughts about how diseased they are, and there doesn’t seem to be any debate that Parkland shooter Nikolas Cruz did just that. Using his own name, Cruz said last September on a YouTube comment thread that he was going to become “a professional school shooter.” Some guy from a Southern state (i.e., not Florida) tipped the FBI through some kind of hotline but the FBI somehow flubbed it. Brilliant.
