What's Known About Robert Bowers, The Suspect In The Pittsburgh Synagogue Shooting

Mark Hetfield, the president of HIAS, told NPR that he is in "a state of shock."

"Refugees flee hate, and for this kind of vile act to happen in our country is devastating, and then on top of that to have it happen in a sanctuary, on the holiest day of the week, is unfathomable," Hetfield said.

"There is simply too much space out there for hate, and it's hatred against refugees; hatred against Jews; hatred against Latinos; hatred against transgendered people; hatred against African-Americans; hatred against the other," Hetfield said. "It's just hate across the board, and there's too much space for it now. Everyone has to stand up to it now. We cannot tolerate this intolerance."
