It was quite expected from a failure that continually blames others for such failure.
The government failed to properly investigate the individual that brought the destruction and killing. Therefore, the government failed to provide the proper security to those victims. As leader of the nation, this means that Obama has failed.
Since he referred to Trayvon Martin as "He could have been my son"; the least he could have done, is to admit that the shooter at the Navy Yard could have been his son.
But as usual, Obama presented his tyrannical agenda brandishing gun control as the answer.
The answer is a strong USA, but it will never be achieved under the Obama Administration of blame while leading from behind.
Washington D.C. is a gun free zone. This means that no one should be carrying. But as usual, the gun free zone was not enough to ensure security for the victims.
So the blame game is lamely the same - failure of the worst kind.
The political banter will swell, but the killing will continue to cause others to wail as the President and his corrupt political agenda continues in respect to security fail.
