Nowhere in his plea does he stipulate to doing these things. Thus my point that you reading quite a bit into his plea. Again, I think he was cruising the bathroom for sex, but you cannot jump to absolute certainty that your description of the events is accurate ON THE BASIS OF HIS PLEA. Again, it's hair-splitting, but you seem inclined to keep shaving away at the follicle, yourself.
His plea is to his disorderly behavior. You can decide for yourself what you feel is disorderly. If constant peeking into stalls is orderly behavior to you, that is your opinion. I am not going to separate out which particular behavior is considered disturbing because neither Larry Craig nor the police do. I take it sum and total as part of the disturbing behavior exhibited and mentioned in the complaint, charge, and guilty plea.
In the short run at least the behavior of the deviants has been exposed. In the long run perhaps disorderly conduct can be used to eliminate these aberrant behaviors in restrooms entirely.
