And people wonder why many are so opposed to bringing a 100K more refuges into this country. If just .1% of 100k are bad that's 100 bad guys to watch and try to prevent from attacking. When there is no need to bring any of them in the first place having open borders is just about as stupid as it gets. I don't have open doors in my house. You enter at my invitation and at your peril if you threaten me or mine. A nation should be the same way.
