So, the NFL Gameday Operations manual says: "no video recording devices of any kind are permitted to be in use in the coaches' booth, on the field, or in the locker room during the game." As far as we know, the Pats did not have a video camera in the coaches booth. Or in the locker room. Did they have a video camera on the field? Depends what you mean by field. See page 5 of the NFL rulebook PDF for a graphic representation of the field: http://www.patscap.com/rulebook.pdf It appears to me that the "field" is the area outlined by the outermost broken line in the diagram. Page 7 of the PDF provides a closeup of the bench area, delineating the "field" from the "media and other" areas. Unless the NFL has published a definition of the "field" that differs from that in the official rulebook, I see no violation as long as the recording device never entered the restricted areas (the field, the coaches box, the lockerroom).
