One of the fundamental tactics for any flack is writing talking points ahead of interviews. This isn’t purely “spin”, by the way — but clients do sometimes get skittish during on-the-air talks. The prep sheet, then, is like a security blanket minus Elmo.
Because of that perfunctory aspect of PR, it’s always easy to tell which clients don’t have proper talking points. When it happens, you sometimes hurt for the spokesperson (a little).
At other times, though, you laugh so hard that you pee (again, a little).
The latter happened when former NSA and CIA major domo Gen. Michael Hayden went viral for all the wrong reasons while discussing ISIS and air strikes.
