Picture this. The lawyers in a legal department have small cameras attached to their monitors. Their clients or primary outside partners also have cameras. Those unblinking eyes let each of them see the other while they talk, if someone chooses to turn on the cameras. Relatively inexpensive, fairly easy to set up, cameras help people get much more out of a conversation than when they can only speak by telephone. A webcam is worth a thousand words.
Even so, I have yet to hear of a legal department with video cameras in individual offices.
