This Swiss guy is, imho, saying the right thing... that the pimp, and also the gal, has withheld the real age and lied to all those ppl who engaged the minor's services. To all who pleaded guilty, well, too bad.. they either didn't want to drag on cos don't want to pump in more money, or believe that they want a closure and for this to end and let ppl forget it over time.. or just think that the court will not allow them to claim otherwise.
This Swiss guy is actually asking the court to show, not only to ppl in SG, but to the world, that the judicial system here is credible. As, if they were to determine that he is guilty.. we could be the laughing stock of the whole world for being a naive and simple-minded buffoons who can't even rationalize on a simple case of lie, deceit and forgery.
