The bereaved teenage son of a Tulsa man shot and killed by a 73-year-old volunteer deputy says his father's killer should have never been on a police force. 'He should have been in a retirement home, not out there on the scene killing my dad,' Aidan Fraley said of Robert Bates. The 16-year-old told NBC he believes everyone on the Tulsa force is to blame for his father the April 2 death of his father Eric Harris and says 'they should all go down.' 'He should have been in a retirement home, not out there on the scene killing my dad': Aidan Fraley (right), 16-year-old son of slain unarmed Tulsa suspect Eric Harris (left) has spoken out to say that his father's 73-year-old killer should never have been deputized and given a gun . 'They should all go down': Fraley (here with his uncle Andre Harris), says all the Tulsa police who allowed Bates to become a cop should be held accountable for his death . Meanwhile, his own mother--who calls Harris her 'soulmate'--has already forgiven his killer. 'The Lord has forgiven me for my sins, and who am I not to forgive him?' Fraley told NBC as she spoke out on the case for the first time. Her young son, however, is not ready to forgive and wants to see the other police officers at the scene brought to justice. 'They were involved in it,' he said. 'One of the dudes had his knee on his head, and I feel like that played a part in his death after the shooting.' Bates has said he mistakenly pulled out a handgun rather than a stun gun when he fatally shot Eric Harris on April 2 as he lay on the ground. He has been charged with second-degree manslaughter. Defense attorneys released some of the training records Saturday for a 73-year-old volunteer sheriff's deputy charged with manslaughter in the fatal shooting of an unarmed suspect in Oklahoma. The records for Robert Bates include certificates showing what training he received, job evaluation reports and weapons training and qualification records dating to 2008. Bates has said he mistakenly pulled out a handgun rather than a stun gun when he fatally shot Eric Harris on April 2 as he lay on the ground. He has been charged with second-degree manslaughter . Terrified: The fatally-wounded man, who is being held by his neck and back by the deputies (pictured), says: 'Oh my god, he shot me! He shot me! He shot me, man.' He then adds: 'Oh, my god. I'm losing my breath' Bates' attorneys said the 64 pages of records released to The Associated Press and other news organizations include records Bates copied and kept for himself. Although there are time gaps in the documents provided, some of the records seem to indicate Bates was proficient in firearms and dozens of other training courses. 'For the first time today, we feel like someone's starting to look at the other side of this as far as his qualifications,' Scott Wood, an attorney for Bates, said after the documents were released. The Tulsa County volunteer deputy has disputed a Tulsa World report that sheriff's office supervisors were ordered to falsify his training records. The World said at least three of Bates' supervisors were transferred for refusing to go along with the requests, and said it consulted multiple sources who spoke on condition of anonymity, but it gave no indication how those sources were familiar with the situation. Bates told NBC's 'Today' show on Friday that he was certified for his position and had the documentation to prove it. Harris' family attorney - who had questioned Bates' qualifications as a reserve deputy - did not return a message seeking comment Saturday. A call to the district attorney's office rang unanswered, and the sheriff's office referred questions to Wood. 'I want to do everything I can to make sure that people know that this allegation of falsified records is not true,' Wood said.
