Firearms lost by and stolen from the police

Dennis R Young is reporting that between 2005 and 2019 640 firearms were lost by the police and public agencies. Lost not stolen. During that same time period 173 firearms were stolen form the police and public agencies. How do you lose 640 firearms?

That's kinda like how the RCMP's terrorist task force *lost* a billion dollars from their budget. That is organized crime. If someone who worked in a bank lost a billion dollars, they'd be fired and go to jail. In 2017 the CBC reported that "RCMP are thanking the public after recovering a lost gun and ammunition that may have fallen from an officer's truck Sunday near the Golden Ears Bridge. They were looking for a 40MM Abrams Airborne Mfg Inc. Less Lethal Multi-Launcher, which a release calls a "gas gun," along with a green camouflage bag containing ammunition. The gun and ammunition went missing Sunday, and the B.C. RCMP said in a statement it believed they fell out of "the insecure back hatch of a truck canopy," shortly before 7:30 a.m. PT on Sunday."
