If a teen stole his/her parents’ alcohol and distributed it to his/her friends, then he/she should be held accountable for providing alcohol to minors, and any other charges that stem from that.I don't agree with underage kids drinking at home either.
Let me ask you this.
Let's say for conversation sake that it was a kid in his stupid stage that took alcohol from his parents stash and gave it to these girls. Is it the adults job to take care and protect him/her then?
If the parents discovered their teen had done this before the other teens left the house, then it would be their responsibility to contact the parents of the other teens and make sure they know their children have been drinking and need a safe way home. If they knowingly allowed the kids to leave while drunk, then they should also be held accountable for the outcome even if they didn’t provide the alcohol.
