The Comitatus guards are elite in every sense of the word. When the privacy 
function is initiated, implanted headware blanks their memory of everything they 
see and hear every sixty seconds. At the end of the day, they’ll remember nothing except accompanying Ohara into his office and then out of it
again. Of course, that function would immediately end if an emergency occurred 
or if they perceived a need to declare a security alert. In either case, they 
would immediately inform him that the privacy function had been discontinued.
