The manifesto written by accused El Paso mass killer Patrick Crusius is the basis for the argument that the shootings were inspired by President Trump. Media commentators, Democratic presidential candidates, and all types of Trump critics have made that case in the days since the murders.

Much discussion was spurred by an article in the New York Times with the headline, “El Paso Shooting Suspect’s Manifesto Echoes Trump’s Language.” The story quoted just 28 words of the nearly 2,400-word manifesto. It noted that Crusius specifically wrote that his views “predate Trump.” And it warned that “linking political speech, however heated, to the specific acts of ruthless mass killers is a fraught exercise.” Nevertheless, the Times declared that even “if Mr. Trump did not originally inspire the gunman, he has brought into the mainstream polarizing ideas and people once consigned to the fringes of American society.”
