If recent history is any guide, if the bomber ends up being a white anti-government extremist, white privilege will likely mean the attack is portrayed as just an isolated incident — one that has no bearing on any larger policy debates. Put another way, white privilege will work to not only insulate whites from collective blame, but also to insulate the political debate from any fallout from the attack.

It will probably be much different if the bomber ends up being a Muslim and/or a foreigner from the developing world. As we know from our own history, when those kind of individuals break laws in such a high-profile way, America often cites them as both proof that entire demographic groups must be targeted, and that therefore a more systemic response is warranted. At that point, it’s easy to imagine conservatives citing Boston as a reason to block immigration reform defense spending cuts and the Afghan War withdrawal and to further expand surveillance and other encroachments on civil liberties.

If that sounds hard to believe, just look at yesterday’s comments by right-wing radio host Laura Ingraham, whose talking points often become Republican Party doctrine. Though authorities haven’t even identified a suspect in the Boston attack, she (like other conservatives) seems to already assume the assailant is foreign, and is consequently citing the attack as rationale to slam the immigration reform bill.
