Buyback has no effect on murder rate

…”Homicide patterns (firearm and non-firearm) were not influenced by the NFA [compensated confiscation], the conclusion being that the gun buyback and restrictive legislative changes had no influence on firearm homicide in Australia,” the study says.

…Politicians had assumed tighter gun laws would cut off the supply of guns to would-be criminals and that homicide rates would fall as a result, the study said. But more than 90 per cent of firearms used to commit homicide were not registered, their users were not licensed and they had been unaffected by the firearms agreement.
