Next time just say no. I always say no. I have nothing to hide but still don't want to be hassled on the side of the road
(And yes, even being an LEO I've had an interdiction unit ask me to search.) he called a K9 unit when I said no, he's like "you're a Cop you should have nothing to hide, why can't I search your car?" I told him I didn't want all my shit strewn on the side of the road and I was tired.
i can't stand the "nothing to hide" lines. the guys i work with are really good about being human, and don't feel like someone should forfeit any rights just because. of course due diligence in an investigation is paramount if there's something to go off of, but giving someone a hard time if they won't let you search when there's nothing to go from doesn't sit well with me.
