I was followed once to my parents house - I was younger and saucier then (or brazen and stupid - you can choose) so I stopped in the drive way and walked up to the cop and was like "are YOU following me"
They said I didn't stop long enough at a stop sign. (GAH) So I demanded to know why they followed me x amount of blocks and never tried to pull me over.
I never did get a ticket but in retrospect - DAMN - fearless back then.
