[NewRomeTacitus]

Considering the money and power of our enemies (and the vociferousness of their human tools) we have to insure that our sources are as reliable and defensible as possible.

Another way to put it:
The big bad hombres would do anything to get us so we need to use the truth as our shield, and we need to make sure that shield stays real clean and shiny with wickedly sharp edges.

"All those who dare to oppose his shield must yield..."
