It would also be cheaper to add an additional layer of security with encryption vs. roving teams of gun toting manhole watchers.
Even if encrypted, you can probably do an amazing amount of traffic analysis to tell when something is afoot. Ask any pizzeria near State Dept or Pentagon. ;)
(That, plus it's easier to break an encryption if you have gigabytes of data to work with, than if you don't have any data to work with...)
