Yes, because officers always politely ask to search someone's car and always inform the person that they have a right to decline.As far as the alcohol incident, I cannot speak to that on experience, however, since you were detained and not arrested, they cannot search your car unless you consent to the search. You must have agreed to the search or else they would have had to get a warrant to search your car. Even if you had a gun case. So, remember, your 4th Amendment right is still protected but I am almost certain that since you probably said "I've got nothing to hide, search my car, I don't care! I'm am/was officer in the military / work for a reputable company" or something of the like, then you consented to the search. If you said, "NO! you can't search my car, I've got rights," then they would have not searched your car until a Judge signed a search warrant based on Probable Cause. Think real hard about what you said in your conversation with the LE personnel while you were being "detained" during your stop, and if it wasn't based on consent, then if you are not too wrapped up with their due diligence to let you go after 2 hours because your BAC didn't go up, then hire a lawyer to address your unlawful search of your car.
What really happens is that the officer usually says something like "Open your trunk." Complying is implied consent, and most people in that situation are too afraid to say no.
