The chairman of the Senate Judiciary Committee is making a new push to apply some U.S. criminal laws to federal employees and government contractors who are working abroad. The move by Sen. Patrick Leahy…is at least the third such attempt since a high-profile killing of Iraqi civilians by Blackwater security guards in September 2007. But this time, Leahy has at least the tentative support of some in the contracting industry and of the U.S. Justice Department. Leahy said…that he was planning to introduce the latest version of legislation soon, and that he will move forward with it if he finds bipartisan support.
