In Chapter Five of Catching Fire we have the following statement from Effie Trinket:
"So, I was just having a peek around because district ruins are going to be all the rage this year, when two Peacemakers showed up and ordered me back to our quarters. One of them actually poked me with her gun!" says Effie.
The title "Peacemakers" seems out of place. Throughout the series they are called "Peacekeepers".
Are there in fact other instances where the term "Peacemakers" is used, such that there is nothing wrong with Effie's comment?
Is this a mistake by Effie, likely meant to highlight her personality and/or that of Capitol citizens in general, in that they can't be bothered to know the correct terms for the people who enforce hardships on the districts?
Is this merely an authorial/editorial mistake?
