Now that the legal opinion has been rendered, maybe a little "social" opinion is in order. Yup, your friend screwed up. Did it do any harm to the kids? No. Would it do any good to prosecute him? No. The parents are over-reacting and are avoiding another important fact... the kids were bugging him to give them a shot. A sit down with all parties involved would be best case (if possible).
The whole having sex after a shot scenario smacks of reefer madness paranoia. Please. Next, it'll be turning into a crackwhore of heroin addict and shots are a starter drug.:jawdrop:
Bingo..man this gives me an idea. I'll have some kids, send them to a party and ask them to beg for a drink, then sue the guy for his house! Free house, and no harm done to me or my kids. Brilliant! Give me a fockin break, this society is retarded.
