A Washington Post op-ed claims:

Nearly all of the mass shootings in this country in recent years — not just Newtown, Aurora, Fort Hood, Tucson and Columbine — have been committed by white men and boys.

However, that's not what the facts say:

Whites are under-represented by race in mass shootings, as are Hispanics, when you look at percentage of total population. Don’t take my word for it, either; look at the stats kept by über-left-wing Mother Jones.

Over-represented are Asians, like Virginia Tech shooter Seung-Hui Cho, One L. Goh, Jeong Soo Paek, Jiverly Wong, Byran Koji Uyesugi and Gang Lu who are all East Asian, and West Asian/Arabs, such as Nidal Hassan, and Abdelkrim Belachheb, whom the sisters dishonestly label “white.”

Also over-represented are black mass murders like Omar S. Thornton, Maurice Clemmons, Charles Lee Thornton, William D. Baker, Arthur Wise, Clifton McCree, Nathan Dunlap, Colin Ferguson, and we’re not even including the DC Snipers, John Allen Muhammad and Lee Boyd Malvo, because they are arguably serial killers instead.

There are some problems with the Mother Jones data, but, this is basically right.
