Yes, realistically, you would have to spend at least the same amount of money, and possibly more. Part of the presentation in terms of the relationship between firearms owners and police was on the whole breakdown of trust between the firearms owners of Canada and officialdom, period.
You have about half the guns in the registry. The other half are out there. Getting the ones that are out there to actually come into the system would be like pulling teeth. People now say that 15 years ago they didn't go into the system, they opted out, and boy are they ever glad they did, they say, “because my buddy had this happen to him, and my buddy's buddy had this happen to him, so boy, I'm glad nobody knows I have them”.
To get those people to come forward now, you would have to go right back to the very basics of the act and change the very premise of the act; the first sentence says that it's a criminal offence to possess a firearm without a licence. As soon as you put the word “criminal” in the first sentence of this, you change the whole demographic.
