US President Barack Obama stepped into is role as mourner-in-chief at the memorial service for the victims of America’s latest mass murder-by-gun, the killings of twelve people at the Navy Shipyard in Washington, DC.

“Once more, our hearts are broken; once more, we ask why,” Obama said during a 20-minute eulogy delivered at the Marine Barracks Washington.  He has delivered similar remarks at the services for the Fort Hood shooting in Texas (13 dead), the Sandy Hook Elementary School massacre in Newtown, Connecticut (28 dead), the bloodbath at the Century 16 Theater in Aurora, Colorado (12 dead), and the mass shooting at a supermarket appearance by US Representative Gabrielle Giffords (D-AZ) in Tucson, Arizona (six dead).  And those aren’t the only mass shootings in America in the last few years.

Obama appeared frustrated with the US political system, dominated by cash from uncontrolled campaign contributions from deep pocketed corporate and billionaire donors.  That keeps even the slightest modicum of gun control from getting through congress.

The US President admitted that changes in the nation’s gun laws “will not come from Washington, even when tragedy strikes Washington,” but only when Americans decide they have had enough of massacre after massacre.

“So the question now is not whether, as Americans, we care in moments of tragedy,” Obama posited, “Clearly, we care. Our hearts are broken - again. And we care so deeply about these families. But the question is, do we care enough?”
