i don't.
if you have nothing to hide, then definitely do NOT consent to a search.
If you have the right NOT to consent to a search, then don't.
Maybe you don't know the law as well as you think you do, and you think you have nothing to hide... consenting to a search is a bad way to find out just how little you know.
You have no obligation on the side of the road to make the officer feel better about you by consenting to a search.
What good can come of it for you? If you have nothing to hide, and you refuse the search, then you're in the same place as if you consent and nothing is found.... BUT....
If the officer finds something * anything * that can be used against you, then the only thing you've possibly done is provided the officer with a chance to use your stupidity against you.
Think about it. The officer isn't digging around your car looking for something to prove your innocence!!!! If you consent to a search you've just give the officer free roam to try and find something to prove your GUILT, not your INNOCENCE.
People who DO have something to hide, often consent to a search under the mindset of "if i say yes, then the officer will feel more at ease and either not really search my car, or not find anything"....
Saying YES to consent to search is the exact reaction of someone hiding something. Don't believe me, go on a few ride along's... or just listen to the stories your cop buddies tell at the dinner table. (nobody said criminals are smart.)
Thank you.
