Last Friday, 13 people were killed at the American Civic Association in Binghamton, New York. The event shocked the nation and was “the worst mass shooting in the United States since the 2007 massacre at the Virginia Tech college,” as New America Media reports. Because the violence erupted at an immigrant service center, the immigrant community has been especially affected, and immigration opponents are predictably using the tragedy to justify, or at least voice, their vitriol toward the undocumented population.
