Security ... think about it!
Does it work? Here's one example from the report: "The Canadian Firearms Program provided support to an RCMP detachment, assisting with a Criminal Code of Canada warrant to recover firearms from a subject who had reportedly pointed a rifle at a co-worker and threatened to kill him." "[It] confirmed the suspect had... nine long guns registered in his name. A warrant was granted and executed, resulting in the recovery of all nine long guns, including the suspect firearm and a quantity of ammunition."
