From right wing talk show host Mike Gallagher:
Gallagher: But guys, let’s look at the inevitable, the 800-pound gorilla in the room. How about we scrutinize young Middle Eastern men to stop this.
Except that this bomber was from Nigeria, not the Middle East. I suppose now you want to scrutinize every African too? We had specific information about this guy from multiple sources. He should have been subject for additional searches because there was probable cause for doing so, not merely because he was a certain ethnicity.
