The way I see Herrimen is more like this strict enforces (as I'm sure others see him like that as well) that forces Bloo and the others to do some ridiculous stuff and be insanely funny as to not get caught by Herriman like in
'Busted' or sometimes Bloo does insanely funny stuff for the exact opposite reason, like as preciously stated in
'Crime after Crime' 
So I'm glad Herriman is there, because if he wasn't, there wouldn't be as much plot driven stories or even laughs
However, I do think is necktie is a bit too tight for even his own good
