I will have to find the crime/murder/prison rates of Canadian resident aliens again, but what I mean by far fewer, is the number of violent crimes and murders per 100,000 committed by Canadian born who are now living as resident aliens in the United States.
For example, the crime rates of some communities in Florida with large populations of ex-Canadians who retired in Florida. When Canadians move from Canada to the United States, they leave a country where guns are very restricted and comparitively less common, and they move into a country where guns are more proliffic.
All other things being equal, any gun control proponent would expect the Canadians moving to the United States to increase his murder and crime activitity, and certainly expect Canadians living in the United States to be much more violent, much more prone to crime and murder than the Canadians he left behind in Canada.
Yet, the simple fact is, that these Canadians who move here do not commit more crimes and murders just because they move to Florida or any other state now that they are no longer under those tight Canadian gun laws, even though they can buy and carry guns just like american citizens can. The United States, most states, allow resident Canadians to own and carry guns after they move here.
The numbers per 100,000 of Canadians who are resident aliens living in the United States have a lower murder/crime/prison rate than the overall rate of Canadians in Canada. (e.g., if the murder rate of Canadians in Canada is 2.0 per 100,000, the murder rate of Canadians living as resident aliens in the United States is only 1.0 per 100,000). The numbers of resident aliens from Canada in United States prisons for violent crimes also experience a lower prison/incarceration rate than all of Canada does.
Generally speaking, Canadians who move to the United States do NOT go on a crime/murder spree when they move to the United States.
They instead experience a lower crime/murder rate than the citizens still in Canada - the only factor changing is moving from a country with tight gun contol to one of less gun control - a direct contradiction to those who maintain that Canadians dont commit as many murders/crime because they are under restrictive gun laws in Canada.
This further suggests, as Michael Moore pointed out, that it is not guns, nor gun laws, nor bowling, nor video games, nor tv, etc that cause people to murder, even when comparing Canada to the United States.
