Federal Bureau of Investigation Director James B. Comey waved his truncheon at the New York Times last week in a concise letter of protest addressed to the paper’s editor. The FBI, denounced in a Nov. 1 Times editorial for impersonating an Associated Press reporter in a 2007 Seattle-area case, had nothing to apologize for, insisted Comey. While the impersonation was “unusual,” he wrote, it was still proper, appropriate, and lawful.
