How is it possible for a suspect to go scold free? first, if the suspect has a higher connections which can be used to protect him from facing charges. Second, if there is no enough evidence to keep the suspect on a trial; meaning that there would be more meetings in the court with the same issue and no clear evidence of conclusion. third, the suspect gets pardon by the person he or she offends, judges, or the supreme king of the country. forth, if the suspect is no where to be found to face justice; finding some suspect is still one of the hardest things to accomplish today. example, where is Osama bin Ladin today? its still a mystery. fifth, if the suspect dies before facing charges, some suspects do commit suicide, some out of natural cause, some even murdered before they get to justice others put justice to their hands.
