EXACTLY! This is Stupid, but for the following reason: A LOT, and I mean a LOT of radical Muslims or other terror types go to Canada or the UK first and obtain citizenship there before entering the US. This is opening the door for them. Many Canadians I have met are of Middle-Eastern, southeast Asian, and African descent. How will they tell? Damn fools.
The only solution is to place the military on both borders and to strictly enforce the law. But I think we both know that won't happen.
