“There is too much of these mass shooting going on in a short time for there to be anything but ‘tin hat’ conspiracy stuff involved.”
Most are simply “copycat effect”. The more news coverage the MSM give these shootings, the more shootings you get, as more people on the edge are given incentive to get their time in the spotlight.
Well, and the more reporting you get, the more local incidents that wouldn’t have been heard about outside their community become national stories. First, the incident establishes a narrative, then reporters jam-fit every other incident into that narrative.
