The murder of Dr. George Tiller has reignited the abortion debate and raised the question: Should violence against medical doctors who perform abortions be viewed and prosecuted as domestic terrorism? NOW ON PBS senior correspondent Maria Hinojosa sits down with two of the remaining handful of doctors who publicly acknowledge performing late abortions, including Leroy Carhart, a fellow doctor in Tiller's Wichita, Kansas clinic. Carhart discusses his vow to carry on Tiller's mission and what it's like for him and his family to live as "targets". The show also investigates claims that law enforcement dropped the ball when it came to stopping Tiller's alleged murderer, Scott Roeder.

Hinojosa travels to Colorado as well to talk with Dr. Warren Hern, another late abortion provider who says he's been living "under siege" for decades. Dr. Hern works behind several layers of bulletproof windows and is now under round-the-clock federal protection.

NOW goes into the eye of the abortion rights storm to see how Tiller's killing and its ramifications are impacting doctors, free speech and a civilized society.
