Along these lines. I took a friend of mine from work shooting this week. He and his son. They are from Montreal. The 20 year old had never seen a gun outside of a video game. We shot everything from a single action 38 to a M1. They loved it.
And more to the point we had a long talk about rights. I explained the county and its blue card. They could relate after a bit because they did the same thing in Canada. And were told it was for all sorts of things but never to take guns away. They wound up losing guns because of it. It is important to continue to fight for our rights otherwise they will sneak more laws in to us because they think we are not watching and working.
I am not sure what your friend misunderstood about the registry laws of Canada, but I just moved from there this past year and never had the government ever tried to take my guns or the many guns in possession of my family members.
There is a gun registry for all hand guns, and there are many more restrictions than there are here. You cannot carry a hand gun open or concealed unless you are on the way to the range and then it has to be in a case and you have to be a member of a gun club.
Hand guns have been restricted for many years in Canada. Most folks weren't allowed full autos - they are considered "prohibited" unless you are a 'grandfather' collector like my father. After he is gone all his 'prohibited' weapons will either have to be given to the government for destruction, have proof that the ability to fire has been removed if you want to keep it as a part of a collection, or let them know that it 'disappeared' many years ago.
perhaps this is the kind of situation where your friend can say guns were lost.
You can open carry rifles during hunting season...although I am sure in cities that would not happen. They did try to do a rifle registry but that was a failed effort. Many of us never registered and those that did wasted their time and money because it was a system destined to fail.
The sad thing is that they think they are protecting people by making so many restrictions... But school shootings per capita are just about the same as you guys have here in the US...the number looks smaller but it's because our population is ten times smaller. They aren't stopping criminals from carrying and somehow they are still able to get their hands on the "prohibited" full auto weapons with no problem at all...meanwhile law abiding citizens have to leave our protection at home.
So glad I am in the US now.
