NO KILLERS FOUND IF THE CASES ARE ON TO OPPOSITION

Most of the assassinate cases on to the sides who are not the pro-government, the murderers have been never found for putting in the justice system which is in the opposite to the actions occured against to the government. Most of the cases against to the government, the authority spent very short time to arrest the doers like the CFF army, The Rebel With Head of Tiger as its Sign, The bomb planter at the Cambodia-Vietnam Friendship Statue, the bomb near by the Defend Ministry etc.
The cases occured to the ones who are not supporting the government, the killers have been never found like The Grenade Bombing on 30 March 2007 to the protesters led by Sam Rainsy, the President of Samrainsy Party, the killing on Piset Pilika who most of the sources released that the cased was related to the top government member, Tat Marina, Touch Srei Nich and Chea Vichea etc. Who are the killers to those peopel? Has the Government done any action to get the killers to the justice? Non of the killers have been found!
