On Sept. 4, 2008, Andrei Borisov was in his Ann Arbor office, waiting for a meeting in which he planned to give his bosses at the University of Michigan documents supporting accusations he had made about a colleague's alleged academic misconduct, among other things. But before the morning was over, Borisov had been forced to sign a resignation letter, arrested for trespassing (in his own office) and for disturbing the peace, and taken from the campus in handcuffs by public safety officers whose presence at the meeting had been arranged, in advance, by his superiors.
