My question involves criminal law for the state of: Virginia
I am at college and a friend of mine was drunk and laying on the ground outside of an apartment. I watched over him while I waited for my other friends to come outside so we could leave. However, there was police car at the other end of the parking lot watching us. After I pulled my friend off the ground we tried to walk to the bus stop and go home. Then the police officer got out of his car and asked us to come talk to him. So when we got over there he said that he saw us both urinating on the ground. I was VERY surprised to hear that because it was completely untrue. After a few minutes of trying to explain that to him he finally accepted the truth. Then the officer wrote down my friend's information and gave him a court date with the charge of "underage possession of alcohol." Next the officer wrote down my information and gave me the same charge and court date.
We did not have any alcohol in our hands or even near us at the time (but I have heard the the body can be considered a container of alcohol). The officer just assumed we had been drinking (my friend did, but I did not). I did not admit to drinking alcohol and he did not breathalize us or do anything to prove we had consumed alcohol. I was very angry so I did not argue over it with the officer in order to prevent myself from saying something I would regret later.
I think this is an unfortunate case of being in the wrong place at the wrong time. I was only trying to help friend get home and now I may get in serious trouble.
So I am here to ask: Do I have any real chance of getting this charge dropped? or should I not even bother trying to defend myself and just accept the inevitable? If I am decided guilty what kind of punishment should I expect?
Thank you in advance for reading.
