you should apply that/your statement to this situation and the alleged domestic violence - are you stating, with certainty, that the RCMP did not investigate the allegation made by the former neighbour - notwithstanding, apparently, the RCMP state/claim they have no record of the former neighbour's supposed complaint. I appreciate you really want to take this discussion away from gun control measures targeting assault-style firearms...
Maybe you should re read the title of this topic.
