Officer: "Do you mind if we search your vehicle?"

failure: "No, but officer this is my brother's car."

Officer: "I guess this is your brother's marijuana too."

failure: "Oh man, I swear I didn't know that was there, this is really my brother's car."

Do people honestly think the cop is going to be like:

Officer: "Oh ok, sorry to bother you than sir. Tell your brother he can't have that stuff when your return his car to him."

Same for when they find crack on someone.

failure: "Officer, that's not mine."

as if the cop is going to be like

Officer: "Oh... Well than carry on. We will try to track down the rightful owner."
