I agree that someone could be perplexed with the hand - I'd probably wonder if they needed toilet paper.  UNLESS the foot touching happened first in which case I'd assume I had a nut case next door.  

I would classify it as offensive. And if there was no one else in the rest room I would classify it as frightening.  

You wouldn't be offended by a foot that wasn't just under the wall, but made it all the way over to your foot?

   I'd suspect that he thought he could slip under the radar simply by copping a plea to disorderly but that going to court would bring terrible publicity regardless of the outcome of the case.

  Hoping that  maybe  no one would  peruse inferior court records in Minnesota and connect a trivial offense to an Idaho Senator-- with a relatively common name-- might seem  a reasonable gamble when compared to the near certainty that it would go public if he demanded a hearing.

 (Might have been a lot brighter not to tell the cops he was a Senator as it is quite possible they'd have never made the connection because no background investgation is likely in such a minor case, but throwing weight around is second nature to most politicians).

A straight plea to disorderly, hoping that no one would notice the underlying allegations, probably looked like the better choice.  And, for three weeks, it seemed to work.  The plea was entered August 8, and did not come to public attention for three full weeks.  

He must have started breathing easier, figuring he'd made it under the radar.  Perhaps, that tinny whistle of fear had quieted down - until The Hill called, last Friday or so, asking for comment.

Wonder who outed Craig's bust?  Maybe a gay staffer at the courthouse, someone tired of his hypocrisy and shameful record of using "family values" votes and speeches to cater to the fundies?

Someone is going to have to write a history of closeted gays some day.  There's so much to work with - including all those people who fed information to J. Edgar Hoover and his partner, and to Sen. Joseph McCarthy for all those years.

Second, any contention that this wasn't exaclty what it looks like is silly.  Craig was clearly cruising.  The Minnesota Monitor has some good information about this restroom in particular.  It seems that it was

"Very cruisy, no security cameras or guards. Most of the time, men will show themselves to you at the urinals and invite into stalls or nearby hotels. Plenty of dark stall action, too!
