Given that the arrest took months to come out in the press, I suspect he was hoping that the incident would pass without being noticed. Quietly pleading guilty to a misdemeanor was probably his best chance of escaping notice.
In any case, I doubt he would have been arrested and charged if there was serious doubt as to intent of his actions. While all this hand waving and foot tapping may be unfamiliar to most, I find it hard to believe that a judge would accept such evidence if they weren't well known by law enforcement as signals used by people who engage in such acts.
I wonder if this cop wasn't aggressively looking to make arrests so the locals can feel like something is been done about the problem. What's most odd is the cop apparently being willing to let Craig go but Craig refused to exit the restroom and was placed under arrest. Sounds to me like that was the conduct which got him arrested not checking a stall to see if the guy who's sat there for 13 minutes is finally done with the facilities!
I wouldn't be surprised if Craig knew the signals or has in fact had homosexual affairs. I don't care. I care about his pompous 'do you know who I am' attitude which I just won't tolerate from public servants. Add in his support for amnesty and he's not worth having around in the Senate gay, straight or just another jerk.
Which goes to show that it is true.
Obviously, they caught him dead to rights
There have been rumors for YEARS that he's gay. I'm pretty sure when you peer into someone's stall for a couple of minutes, get into the one next to it, put your feet into it and wave your hand inside, the intent is clear.
