Most cops would laugh in your face and forget about cutting you a break on that taillight violation, but if your luck is very, very bad you just be dealing with one of the tiny handful who would very carefully, by the book, run you in for fleeing on foot, resisting arrest, possession of a controlled substance, and possibly wipe the bad attitude off your face with a flashlight.
Travel with caution.
I'm talking about serious situations...not stops involving a broken tail light.Of course you're not gonna threaten to sue a cop for millions over a minor issue like that.OTOH if you're being seriously abused...detained without just cause,for example...you just might do so.
