The Vail School District in Arizona has been forced to add extra security to protect teachers and students at Cienega High School after they posted a picture to their Facebook page showing a math teachers’ group Halloween costume. It was meant as a math joke, t-shirts that looked like they had blood stains on them with the words “Problem Solved” on the front, but it was interpreted by Charlie Kirk’s own organization, Turning Point USA, as mocking their late founder’s assassination. Even after the district posted an explanation and photographic proof that the teachers had worn the same costume the year before, some conservative activists and prominent national leaders doubled down, posting the teachers’ names, phone numbers and demanding they be fired. The school has had more than 3-thousand hateful messages, including death threats, with the school superintendent asking for better understanding.
