To experts in the field, the El Paso rampage was predictable. Frank Figliuzzi, a former head of counterintelligence at the FBI, wrote in a column published just four days earlier in the New York Times that Trump’s words eventually could incite bloodshed.
“The president has fallen short of calling for overt violence against minorities and immigrants, but unbalanced minds among us may fail to note the distinction,” Figliuzzi wrote. “If a president paints people of color as the enemy, encourages them to be sent back to where they came from and implies that no humans want to live in certain American cities, he gives license to those who feel compelled to eradicate what Mr. Trump calls an infestation.”
