The Boston Marathon bombings are closer to the colloquial and legal definitions of terrorism than the Aurora shooting, but not the Oklahoma bombing, or the Arizona attack.
The real difference is that Mr. Tsarnaev is a Muslim, and the United States has since the 9/11 terrorist attacks constructed a separate and profoundly unequal system of detention and punishment that essentially applies only to Muslims.
