This one is suppose to be a true story...
One day Trooper W. spotted a woman riding a motorcycle topless down the highway and he pulled her over. He called into Crawford Co. dispatch, and was overheard by all the LEO agencies in the county who were too small and poor to have their own dispatch system, to get the appropriate statute for this obvious transgression. However, there were no laws on the state books about women driving topless, nor were there any county ordinances against it.
The county dispatcher, eager to help the befuddled trooper realized that Missouri DOES have a helmet law for motorcyclists and so asks Trooper W., "Is she wearing a helmet?"
To which Trooper W. replied over the radio for all to hear, "I don't know, I'll check and see."
