As we noted in our review of the documentary, JFK: One PM Central Standard Time, Walter Cronkite's breaking-live broadcast of the Kennedy assassination was significant for his rigorous reporting of what were confirmed facts, and just as rigorous reminders of what were not, even though they were thought to be reliable. It's a classic news journalism lesson for any era, especially our current one of instant internet news delivery. The broadcast, shown here in excerpts, is also remarkable for the technologies used, primitive by today's standards, with CBS going on air before the old tube camera had completely warmed up. Cronkite was on the air for over an hour before he delivered (at the end of this clip) his well-remembered emotional moment, confirming that the President was indeed dead in Dallas. –Eric Gould
