From The Houston Chronicle: 

Federal law enforcement officials told the Associated Press that Hasan had come to their attention at least six months ago because of Internet postings that discussed suicide bombings and other threats.

One of the Web posts that authorities reviewed is a blog that equates suicide bombers with a soldier throwing himself on a grenade to save the lives of his comrades.

“To say that this soldier committed suicide is inappropriate. Its more appropriate to say he is a brave hero that sacrificed his life for a more noble cause,” said the Internet posting. “Scholars have paralled (sic) this to suicide bombers whose intention, by sacrificing their lives, is to help save Muslims by killing enemy soldiers.”

The officials say Hasan appeared to have made the postings, but they are still trying to confirm that he was the author. They say an official investigation was not opened.

Why wasn’t Hasan investigated more aggressively?  Hasan’s conduct seems to have raised red flags at least six months ago.  This tragedy could have been avoided if investigators took seriously his threats and bizarre comparisons.  Imagine if a solider had made pro-Communist/anti-American comments during the Cold War.  They would have been immediately investigated.  Was Hasan not investigated because of political correctness?  It’s hard to know for sure, but it’s certainly a possibility.  Stephanie Gutmann at NRO asks:  “How many more victims of political correctness can we afford?”  The Fort Hood shootings are a grim reminder that the greatest threats to U.S. national security come from within.  This was not a man-made disaster.  Radical Islam has struck again in the United States.
