hmmm, lets see, someone breaks into my home with a crowbar, looks around the house, finds me and my children and I start shooting and I am supposed to count the number of times I squeeze the trigger? Okay, since the events surely took place in a slow, orderly and predictable way, I should have known better and only slapped him, and only once, wouldn't want to bruise him. /s
The border between the US and Canada is, according to Wikipedia - "The Canada
–United States border
, officially known as the International Boundary, is the longest international border in the world shared between the same pair of countries. The terrestrial boundary (including small portions of maritime boundaries on the Atlantic
, and Arctic
coasts, as well as the Great Lakes
) is 8,891 kilometres (5,525 mi) long, including 2,475 kilometres (1,538 mi) shared with Alaska
. It is Canada's only land border
The border includes some very isolated regions, mountains, woodlands etc., and would be very difficult to effectively stop the flow of illegals weapons or anything else for that matter.
The border between the US and Mexico is according to Wikipedia - "The border, separating Mexico
and the United States
from each other, traverses a variety of terrains, ranging from major urban areas to inhospitable deserts. The border's total length is 3,169 km (1,969 mi), according to figures given by the International Boundary and Water Commission
It is the most frequently crossed international border
in the world, with approximately 350 million people legally crossing per year."
Again a very long border and difficult terrain. The US has been unable to stem the flow of illegal drugs and immigrants. Though a lot of illegal weapons cross the border from the US into Mexico, that would quickly change if guns were banned in the US, the demand and profits from that demand would provide an incredible incentive for the drug cartels to also become weapon cartels, and they certainly have the finances to start such an enterprise.
