Suggestion Police Car Megaphone

[Chezburger]

Not sure if this is on the burner anywhere or if it'd be possible but having a megaphone officers can use whilst in the driver's seat/front passenger would maybe be useful for chases, gathering the attention of multiple people, clearing out an area for a police response, whatever other uses they may have

I actually love this idea, never have seen it done before
