The article says "The refugees, many from Somalia, have been crossing an unguarded section of the Canadian border in northwest Minnesota on an almost daily basis for months now".

That's interesting. The Muslim al Shabaab extremists in Somalia have been encouraging Somali and other Muslim sympathizers in the U.S.A. and Canada to attack soft targets like shopping malls and to use every means possible to attack, maim and kill non believers in the U.S.A. and Canada.

Why would Canadian police and immigration officials take the risk and allow Somalis to cross the border illegally into Canada to claim refugee status?

And, once in Canada, how will Canada deport the migrants if they don't meet the criteria to stay in Canada?
