According to ABC anchor Diane Sawyer, a new Oklahoma law making it a felony for U.S. citizens to knowingly provide shelter or transportation to illegal immigrants goes "across the line," "too far," and turns people into "vigilantes." Interviewing Lou Dobbs, CNN host and noted opponent of illegal immigration, on Tuesday's edition of "Good Morning America," Sawyer appeared to be aghast at what she considered "turning people in" for offering assistance to illegals.
