Re: Second Amendment
"Canada had bomb-checking of laptops decades ago, long before the Americans. They would swab the keyboard and other areas for traces of explosives. But AFAIR they stopped doing it quite some time ago"
They had engineering documentation that essentially made the point that to do sufficient damage, most laptop bombs *would never be bootable* as a normal computer. They switched to "power it on so we can see it boot". Which, in a number of locations, they ask that your phone do the same. If it happens to be without power you loose it till you leave the location or get off the plane.
