The Great Wall of America? Officials ‘considered building fence on northern Canada border to keep out criminals’

The U.S. has considered building a fence along its northern border with Canada to keep out terrorists and other criminals, it has emerged.

A Customs and Border Protection Agency report suggested fencing and other barriers along the longest non-militarised open border in the world.
But the U.S. agency has since said it is more concerned about considering the environmental effects of building more infrastructure along the border.
