Have you thought out every aspect of your post? Does adultery really disturb public order enough to execute someone? Okay, if it's an Islamic state, then Sharia must be implemented but are you honestly saying that every alleged adulterer was really guilty? Doesn't the Islamic justice system put the burden of proof on the prosecution and not the defense? Rape victims have been executed too whereas the rapists got off with a slap on the wrist (but I won't get any article because it will be dismissed as Zionist propaganda). I remember reading here that the prosecution needs four witnesses minimum to even bring a case to court. Only way to prove that is if they were out in public together showing affection unless they look through the window of a private house, which is forbidden.
