This is a difficult article, and it will be hard to make it pant-wettingly funny.
I do think, however, that you do a good job. I love the underlying theme of
policework involving filling in forms, with the pen as their main weapon. I think
there can actually be more done here, perhaps portraying "paperwork" as a major
enemy of the police, requiring armies of officers working on just that.
The section about the history is golden. I love the subtlety.
I see some people mention on the talk page that we need "more doughnuts". I don't
think that is a good idea at the time, and I think you did very well to steer clear
of it. That is a predictable cliché that should at best be included only in the footnotes.
What you did is much better.
I am scoring the humour with a 7, because I am stingy with points. I think there is still
room for improvement (will mention some suggestions below), but what you did here is
already a great article in its own right.
