Fifty-year-old New Jersey resident Karen Waller was arrested today by the FBI’s Joint Terrorism Task Force for her allegedly aggressive letter-writing campaign, which included 50 threats mailed to the U.S. Supreme Court, along with her local township, police department, and Rutgers University. “All of you Supreme Courts Judges will pay with death,” read one letter signed “Karen,” in script, along with Waller’s home phone number. “Do not push my buttons,” the notes said. “Do not disregard this letter. Do not underestimate me period!!! … Lights out!!!” No ricin, at least.
