A jarring image shows authorities rushing to help two West Virginia National Guard members just moments after they were gunned down by a crazed shooter in Washington, DC, Wednesday afternoon. Footage captured by CBS News showed the two brave troops lifeless on the ground as scores of law enforcement officers, including cops and Secret Service agents, surrounded them during the chaotic moment.
