In a recent report by Amnesty International it states that: "It destroys the person. Torture, sickness and death in Syrian prisons." Such crimes are known as 'war crimes' or 'crimes against humanity'. Imagine that someone you know, or someone you meet, is under suspicion that he or she is guilty of war crimes. What can you do? You can of course choose to do nothing, but the majority of people believe it is a moral and lawful duty to report these war criminals.
You can do this by the police. But you do not have to go to the police to do this. You can also report the person by e-mail or via the police website about war crimes. And of course you can do this anonymously if you prefer.
