This is very simple and very consistent with the behavior of a narcissist.
The shooting at Newtown offered an opportunity that could be exploited by Obama in support of his gun control agenda. Lowering flags across the country was as good as a good pro Obama report on local news. Everything that this guy does is in support of his larger agenda.
On the other hand, he could care less about the murder of Marines and Sailors. Especially when that is done by those that he view as allies and supporters. He wants what happened in Chattanooga to be shoved down into the memory hole.
Narcissists and megalomaniacs have pathological brains, we cannot comprehend how they think and how they will behave. But when they manage to get in positions of power, millions of human beings tend to die.
I’m curious whether the flags in New Jersey are at half staff.
I remember that Krispy Kreme gave the order for them to be lowered to honor a crack head singer.
“Why did Obama not order flags at half-staff after Chattanooga?”
Ah - here’s another thumb in your eye, America....
Hussein has ALWAYS signaled loud and clear that he REJOICES when Muslims shoot, behead, burn, drown, etc., Christians or Jews.
