Chuck Schumer wants to do just that. It sounds oh so reasonable, right? U.S. Sen. Charles Schumer is calling for passage of legislation prohibiting individuals on the U.S. terrorist watch list from buying guns. The New York Democrat noted the arrests this week of three Brooklyn men on charges they conspired to join ISIS in Syria or carry out attacks at home. If they were on the terrorist watch list, the bill Schumer’s backing would have prohibited them from buying firearms or explosives.
