Fresh on the heels of a member of one right-wing militant group opening fire on students, another right-wing militant group is, without even pretending to seek permission, setting up armed “guards” to “protect” schools, presumably from people very much like themselves.
Assuming this is the same Oath Keepers that’s pulled stunts like these in the past, here’s the con they’re running: Some bloody event has claimed national headlines and they weren’t at it, so people continue to not care about their message. So they try to stir up another bloodbath, so that their members can use their presence at the next massacre as a media platform to spout their worldview. And this time they’re doing it at schools.
As far as I’ve seen there is no confirmation that Cruz was a member of a militant group. Early on there were reports that he participated in a white supremacist organization but that story hasn’t held up according to reports.
From what I read about the Oath Keepers, there’s plenty to find objectionable but where is the evidence of the “con” to which you allude?
As long as they’re not on school property and otherwise not violating the law, school can’t do anything.
