I almost got arrested for public intoxication one time. I didn't think I was as drunk as I actually was, and I lived a few blocks away from the bar. During the long walk home, I felt like taking a few illegal shortcuts through private property. One of the homeowners must have reported a trespasser to the police, and a squad car stopped in front of me about 100 yards from my apartment.
The officer was professional about the whole thing. He explained that public intoxication was a misdemeanor, and that he had the right to take me into the station if he thought I was a menace to the public. I told him I was sorry for taking those shortcuts, and that I just planned to go home and sleep it off. He let me go with a warning, only after he walked with me the rest of the way.
