There is a story of the arrest and charging of someone who commented on police action occurring in public from their private balcony with public intoxication. The charges were dropped, and a lawsuit is ongoing suing the police, but it raises the question of exactly what makes something public.
Exactly what makes the state of intoxication "public" for the purposes of public intoxication laws?
The event occurred in Newport, Kentucky but answers for any jurisdiction worldwide would be of interest.
