Witness is a person who sees an event or something which is against laws and rules of state. Witnesses identify criminal, thieves and help send them to prisons and as such their life is in danger. However, in world it has been made first and foremost to protect the witnesses.
In Pakistan many witnesses were killed and kidnapped in the murder cases of prominent personalities. Sabeen Mahmud was shot dead in a target attack and no witness came forward to identify the killers. Likewise many witnesses were killed and threatened by terrorists just because they were not protected. Therefore, eyewitnesses never come forward to identify criminals in Pakistan. To make sure the protection of witnesses in the country government should take some practical steps for them and stringent laws must be implemented as soon as possible.
