My question involves criminal law for the state of: South Carolina
I am 17 years old and reside in Virginia. I just graduated from high school, and my friends always go on a trip to a beach in South Carolina to end the school year. I know there will be alcohol in the beach house that we all stay in and was planning on not drinking and staying out of trouble. However, upon reading the SC laws on underage alcohol possession, I'm getting worried about even going on the trip. The law talks says "It is unlawful for a person under the age of twenty-one to purchase or knowingly possess alcoholic liquors. Possession is prima facie evidence that it was knowingly possessed."
Is it possible for me to get in trouble even if I'm not drinking at all and none of the alcohol inside the house is mine?
What exactly does "knowingly possessed" mean?
A concern of mine is getting in trouble while I'm sleeping upstairs while in the same house as kids who are partying. Is it possible for me to get in as much trouble for them simply because we are under the same roof?
Any help/advice is appreciated!
