If a cop pulls you over for speeding, and he asks you if you are willing to open up your trunk, you have a few options. You can do it, because you know you have nothing in there, and you don't feel like dealing with bullshit. You can refuse, because you are principled, and you know your rights, and you are going to make that cop think long and hard before you give up those rights. Or you can refuse because you've got a pile of dead hobos covered in your ejaculate and feces in that trunk, and you don't want the cop to see that shit.
When the NFLPA asked the owners to open up their books, and they refused? The NFLPA smelled dead hobo and old man jizz.
