Obama is certainly evil enough to murder large numbers of innocents to advance his agenda. However, I see no reason to seriously consider the suggestion that Obama is responsible for these particular brutal killings. Brian Terry's murder and the other deaths associated with Fast and Furious are an entirely different story, and I am firmly convinced that Obama personally approved the criminal acts that led to those murders. Obama is a brutal, evil, murderous thug, but we should only give him the blame for his own crimes; he's not the only source of evil in the world.
There are many examples to prove your point.
Look what the Nobel Peace Prize winner did to Libya. He redefined "Enforcing A No Fly Zone" to mean "Carpet bombing" an entire nation.
He and Eric Holder are no different than Janet Reno. In order to save the children from the "evil man" they burn everybody up (including the children).
