The FBI's Magic Lantern

The application also asks permission for the FBI or its delegated entities to enter the location "surreptitiously, covertly, and by breaking and entering, if necessary"—and "as many times as may be necessary to install, maintain and remove the software, firmware or hardware."

So a precursor of the Magic Lantern was in use back then—under Clinton's FBI—and it is Jim Dempsey's belief, and mine, that the state-of-the-art Magic Lantern is now in the field, among us. The FBI already told Reuters in December that it uses keystroke loggers. So beware of what you stroke.
