November has been a crazy month.

In two weeks, more than a dozen campuses targeted by threats of violence

The day after the University of Missouri’s president resigned following a series demonstrations over racism on campus, violent threats appeared on the anonymous messaging app Yik Yak. “I’m going to stand my ground tomorrow and shoot every black person I see,” one of the more alarming posts read.

That same day, another Yik Yak user threatened violence against black students at Northwest Missouri State University. A few days later, someone claiming to be a Missouri student threatened to kill black students at Howard University. Then, another Yik Yak user threatened to kill black students at Michigan Technological University. And last week, an anonymous user posted messages on Twitter, threatening to “shoot every black woman and male I see at Kean University.”

In the past two weeks, such threats have been made against more than a dozen colleges and universities. While many of the threats have targeted black students amid a growing campus protest movement, others seem to have been designed to capitalize on fear generated by the recent terrorist attacks in Paris. Some of the threats have been made against students at institutions that have attracted widespread attention for protests over racial issues, while others have been against institutions that have not had such protests.
