Literally all are clearly HPs based on the things they have done on-screen in the series.
Meg? Joe? Sneakers O'Toole?
IIRC Meg tried to sexually assault Brian and was going to let that football player unknowingly rape Chris; Joe has engaged in police brutality on numerous occasions.
It's an animated sitcom; it's meant to be taken lightly and it's often done ironically or as a way to lampoon or parody American culture (you'd appreciate a scene once where the police completely ignored Peter and Brian despite the fact that there was very clear evidence of murder, but then arrested them for possession of a small amount of marijuana). This post is just utterly hilarious, though I think you meant it seriously and didn't intend for it to be funny (which makes it 10 times funnier
)
