It was the unfortunate result of a mistranslation of the rifle's name by the RCMP. They translated it as 'of Dragons', as in, to be used by dragons to oppress mankind. This was influenced by the oversize trigger guard that was assumed to be designed to accomodate dragon talons. Had the authorities consulted the proper experts, they would have clearly seen that the length of pull, eye relief, and scope height are out of all proportion to dragon anatomy.
The correct translation is, of course, Dragon-Off, as in to be used in the deterence of, and defence against dragons and dragon attack. The oversize trigger guard is designed to accomodate winter gloves, as used by people in remote northern areas most susceptible to dragon attack due to lack of formal air defence.
I think the RCMP has realized their error in this regard, but instead of lose face by reversing themselves, they are proceeding to allow more semiautomatic .50 rifles to come into the country non-restricted. these guns are quite cost prohibitive for individuals. I only hope that small communities will be able to pool their resources and purchase a few, so that canadians are no longer easy pickings for rogue dragons.
