Commentary: Obama's "routine" on mass shooting exposes failure of U.S. politics

The Americans were startled once again when tragic news break out about the deadly campus shooting in Oregon on Thursday.

However, the United States is "the only advanced country on earth that sees these kinds of mass shootings every few months," just like President Barack Obama has painfully acknowledged.

Obama, angry and frustrated, criticized that the nation's response to mass shootings has become "routine," from press coverage, to his own comments, to the fruitless debate over gun control.

It is obvious that the country has grown "numb" to mass shootings like Thursday's incident in Oregon, where a 20-year-old gunman killed at least nine people at a community college.

There have been 296 shootings so far this year in the United States, claiming more than 370 innocent lives, and it was the 15th time Obama has pleaded for gun control legislation since taking office in 2009.

How come a country as powerful as the United States has been unable to stop this kind of brutal attacks against innocent civilians?

The problem is deeply rooted in the country's political system, where bipartisan politics and interest groups exert huge influence, to the point that security of the American people have to give way to political correctness and corporate interests.

Opinion polls have repeatedly shown that an overwhelming majority of Americans favor stricter gun control rules, yet no legislation on that front can be expected in the near future.

Even the Newtown massacre in 2012 that killed 20 children and six adults failed to break the impasse in Washington over gun control.

The biggest surprise to the world in the wake of Oregon shooting is that there was no surprise for such cold-blooded murders to happen again and again in the United States.

Defects in the U.S. political system have not only caused inaction, but also panic that alarmed the world, as an imminent government shutdown resulting from political wrestle on the Capitol Hill last month posed danger to both the U.S. economy and the world market.

The recurrent mass shootings in the United States deserve real reflection and pondering, since those innocent lives cannot be lost in vain. Endi
