Fifty-one pages of confidential police documents released by the Tucson community college Jared Lee Loughner attended give detailed descriptions of his behavior, offered by fellow students, instructors, and campus police: Loughner was disruptive in class, often speaking out of turn or making nonsensical assertions. He once insisted that the number 6 was the number 18 and, in an act that got him expelled, made a YouTube video calling the college "the biggest scam in America" and linking it to genocide. Campus police officers wrote in their reports that they believed he might be mentally ill, while others described Loughner as "creepy," "very hostile," and having a "dark personality." When two police officers delivered a letter about Loughner's suspension to the young man's home, they requested two additional officers be posted in the neighborhood.
