I'm taking a business law class, and today I learned officially that cops really can't check your trunk or glove compartment if they're locked when they pull you over. They can check the rest of the car though, without a warrent. You can actually refuse to open your trunk, and if you do open it, you waive your 4th amendment rights.

I think I sorta heard that before hearing 99 problems, but not from an official source. I'm not saying that Hova isn't official, but you know.
