David Kris, a Associate Deputy Attorney General from 2000 to 2003 who first came to prominence following his biting analysis (.pdf) of the legality of the government's rationale (.pdf) for its warrantless wiretapping program, submitted to Congress a stunningly detailed reading (.pdf) of the government's proposal (.pdf) to update surveillance laws and shift power from courts to the executive branch.
Kris pays particular attention to how the law currently defines electronic surveillance (very confusingly see chart below) and how the proposed bill would change those definitions. Kris finds a problem in the definition of surveillance as only activity that is targeting a "particular, known" person.
Apologies to Kris, but I think that's exactly the point. It's exactly the position held by scholars such as Judge Richard Posner and Kim Taipale.
