Guns silent in Australia 20 years after Port Arthur massacre

A file photo taken on September 8th, 1996 shows Norm Legg, a project supervisor with a local security firm, holding up an armalite rifle similar to the one used in the Port Arthur massacre and which was handed in for scrap in Melbourne after Australia banned all automatic and semi-automatic rifles in the aftermath of the Port Arthur shooting.
