What you're suggesting is right in the wheelhouse of the fact-finding purpose of juries (or a judge if they opt for one).Doesn't there have to be a demonstrable bargain made? E.g. the guy says, "I will give you $100 if you [perform oral sex on] me." Alternatively, the woman says, "I will [perform oral sex on] you for $100." And then the other party, man or woman agrees and they get on with it?
So advancing the logic, if Kraft got his massage and the woman gave him his tug and he left a "tip" with no bargain spoken or implied, is he still guilty?
Based on the evidence submitted at trial, does the jury feel the state has proven, beyond a reasonable doubt, that Kraft knowingly exchanged money for sex, and thus violated the statute? Or do they read the evidence as containing some ambiguity that leaves them with a reasonable doubt as to whether or not Kraft engaged in soliciting/accepting prostitution?
But, as a matter of FL law, no, it's not dismissible on those facts. A "nudge and wink" transaction is still a transaction that goes to the jury for a final determination.
