Hurry in, 0 apr for 60 months on some models and a 1,000 contract bonus. Number one in good evening. Tonight new details about the radical young married couple who walked into a pizza parlor this weekend, ambushing and killing two Police Officers at point blank range. Were now learning more about who they were and the possible warning signs that this was no ordinary husband and wife. Heres abcs ryan owens on their mission to start a revolution and the message they left behind. We have two officers down. Were performing cpr on both of them at this time. Reporter those two Police Officers never saw it coming. How could they . A sunday ambush by a Young Las Vegas couple heavily armed and hellbent on murdering police. Tonight, those faces of hate. Cop killers jerad and amanda miller. He was 31. She just 22. Their spree would leave three innocent people dead, a community stunned, and that question. Why . We believe that they equate government and Law Enforcement fascism and those who support it with nazis. Reporter at 11 22 sunday morning the millers ambushed those two Police Officers at this pizza restaurant as they ate lunch. They executed both men. Then draping their bodies with a dont tread on me flag, pinning a swastika on them and a note that read the revolution has begun. I saw the gun in their hand, and he just told me to tell the cops that it was a revolution. Reporter the couple didnt stop there. They took the officers guns and ran to this walmart. A whole bunch of people start running toward the back, like the main exit, or the emergency exit. Reporter five minutes later at 11 27 they shot and killed an Armed Civilian who confronted them. Then as police moved in the couple carried out a suicide pact. Amanda shot her husband several times, then shot herself in the head. The couples postings on social media are filled with Second Amendment patriot rants against what they call a fascist government. The Southern Poverty Law Center tracks that sort of speech online. The Patriot Movement has grown absolutely explosively in the four or five years since barack obama came on the political scene in this country. Reporter in the days before the rampage miller posted a series of comments on his Facebook Page indicating that in order to restore freedom to the United States the best men would strike for a free and just world with our blood, sweat, and tears as payment. He also said there is no greater cause to die for than liberty. I will willingly die for liberty. Clearly, he felt that the war against the government had begun. People who inhabit these groups by and large are very, very angry. The vast majority of them are not going to go out and murder Police Officers. But theres a pretty substantial subset of those people who are willing to engage in violence. Glass t that is the courthouse. Reporter jerad had a lengthy criminal record and ranted on youtube about his house arrest, calling the county courthouse a monument of tyranny. Sounds a little like nazi germany to me. Reporter he was paranoid about government wiretapping and drones. Theyre already wiretapping your phone, you know, watching your facebook and everything. Paranoia is really an integral part of the militia groups in particular. These are groups that thrive on conspiracy theories that have no basis in fact. Reporter in april the millers joined other antigovernment protesters at Cliven Bundys cattle ranch a few hours away. Heres jerad talking to reno affiliate krnv about the standoff against federal agents over grazing fees. I feel sorry for any federal agents that want to come in here and try to push us around. But if theyre going to come, bring violence to us, well, if thats the language they want to speak well learn it. I think that jerad millers presence at the Bundy Standoff is extremely important to trying to understand what happened in las vegas. I think it is very possible that jerad miller saw it as the opening battle in a revolutionary war against the government which he intended to continue. Reporter Cliven Bundys son says the millers were asked to leave their ranch because even they considered them too radical. Some of the couples closest friends here in las vegas say they actually talked about killing cops all the time. Neighbor kelly fielder says the millers were staying at her apartment right before their killing spree. They had, i mean, a cart full of just ammunition, ammunition, guns, everything. Reporter fielder says shes now riddled with guilt for not calling police. Especially considering some of the couples facebook posts. Last month amanda wrote, to the people of the world, youre lucky i cant kill you now. But remember, one day, one day i will get you. And on the day before their rampage jerads final post. The dawn of a new day. May all our coming sacrifices be worth it. The real sacrifice . Three innocent people murdered. Joseph wilcox, the civilian who confronted the couple at walmart. Ive been waiting for him to walk inside the house, and hes just not going to. Reporter and those two las vegas Police Officers, alyn beck and igor soldo. Both husbands and fathers. Beck leaves behind three children, and soldo a new baby. Im ryan owens for nightline in las vegas. Thanks to ryan owens for that report. Next, Diane Sawyers exclusive interview with hillary clinton.

New york is really our home. Reporter Hillary Clintons house is a reminder of the drama shaping her life. The chicago girl who became a star of yale law school, the transformation into a political wife of a charismatic candidate for governor of arkansas. Its not an image question so much as a priority question. Reporter she also describes what she says was her proudest moment as secretary with the president , the decision to go in and get Osama Bin Laden. My heart was in my throat because we were watching on the video screen what was happening, and we saw one of the helicopters tail clip the wall as it tried to get into the compound. You really didnt tell president clinton about Osama Bin Laden . No. When president obama called to tell him, i think the president started by saying Something Like i assume hillarys told you. He goes, told me what . Reporter as we sit together, an old stress has returned. An essay in a magazine making headlines, and political opponents warning they think the topic is still fair game. Monica lewinsky. Mm. Is back in the news. Well, shes perfectly free to do that. She is in my view an american who gets to express herself however she chooses. But thats, you know, not something that i spend a lot of time thinking about. Really . Really. Yeah. I mean, i wrote about it in my book, living history. I dealt with it at the time. I have moved on. And thats how i see, you know, my life and my future. Youre not looking at me thinking, here she is asking these questions no. Because i knew you would. I knew youd have to. Its something in the news. You have every right to ask. And i have every right to tell you how i feel. Did you call her a narcissistic loony toon .

Reporter tonight Hillary Clintons 66 years old. Wow reporter on a schedule almost as taxing as a campaign tour. She and her husband, thanks to some big spenders, including wall street companiesr no longer the couple struggling for money. Reportedly, they can charge hundreds of thousands of dollars for speeches. It has been reported youve made 5 million making speeches, the president made more than 100 million . Well, if you you have no reason to remember, but we came out of the white house not only dead broke but in debt. We had no money when we got there, and we struggled to, you know, piece together the resources for mortgages, for houses, for chelseas education. You know, it was not easy. First of all, we had to pay off all our debts, which you had to make double the money because theres obviously taxes and then pay off the debts and get us houses and take care of family members. Do you think americans are going to understand five times the Median Income in this country for one speech . Well, let me put it this way. I thought making speeches for money was a much better thing than getting connected with any one group or company, as so many people who leave public life do. Reporter the day is winding down. While she says shes still looking ahead to what is possible and what she would leave behind. I probably have as good a sense of how hard the job is as anybody. Age. Age, yes.

It matters. Age matters. It may depending upon who the person is. My mother lived with us until her death at 92, and she was as active and involved and just curious and intellectually capable as people much younger than her. So its the individual. When are you going to decide whether youre running for president . You know, im going to decide when it feels right for me to decide because by the end of this year . Well, certainly not before then.

Can a single show change the way we watch television . All because of some very active and engaged fans. Abcs nick watt takes us behind the scenes of Pretty Little Liars. Reporter Pretty Little Liars is a salacious little show about a high school posse, a missing friend named alison, and a faceless nemesis named a who torments the girls as if from beyond the grave. It stars young women. Its aimed at young women. And i think we are changing the way people watch television, and i think these millennials are going to grow up and continue to watch television in this way. Reporter a bold statement from the show runner. Pll as they call it is the most tweeted about show on tv. The show has twitter followers in the millions. The stars 10 million followers between them. They are huge on social media. Huge. I think without that aspect our show would definitely not be where its at. Reporter lucy hale, who plays aria, is right now launching a Country Music career off the back of her pll popularity. No one to save you but yourself reporter Troian Belisario who plays alpha spencer, has been acting since age 3. Her dad created magnum p. I. But boy, have times changed since sellecks mustache ruled the air waves. Being on social media is very much a part of my job. Part of your job. Yes, it is part of my job. Do you guys respond to the feedback on social media . And does that then shape where you take the show . Oh, immensely. Hanna watch out. Reporter they delve deeper into mysteries. Youre too much. Reporter created even higher cliffhangers. Because fans ask for it. It is a giant test group of millions of fans every night. Reporter pll is about to kick off its fifth season on abc family. So whats it actually about . Well, i think that it plays on a very important piece of adolescent psychology, which is that when you are this age it feels like the world is revolving around you. People either hate you or they love you. Were actually the manifestation of those insecurities. They did warn me that you were the smart one. Sorry. We also have lots of hot guys with abs. Does that help . You auditioned for this role, right . I did. Reporter Sasha Pieterse plays queen bee alison who disappears, they think shes dead, then she returns. I thought you were dead. Yeah, i heard that too. But here i am.

Shay mitchell plays emily, whos wrestling with her sexuality. Definitely with my characters storyline, the way she came out and had the support of her friends and family, which is what it should be, i think it was great and it helped it did help a lot of people. And theres some racy stuff. Lucy hales character has an affair. Review it now. So i know im on the right track. Reporter with her english teacher. I mean, thats wrong on many levels. But we checked. I guess its pennsylvania where the show is set, its not. Its not illegal . Its not. Its frowned upon. Its definitely frowned upon. No. I cant take that. Reporter that plot line, which plays out right here in the teachers apartment, is straight from the books the series is based on and was kept in as a result of online fan pressure. Theres fan pressure and direction over every little detail. The costumes. I put spencer one time in blackandwhite stripes. I didnt hear the end of it because only aria, only aria wears blackandwhite stripes. Are you still hating on me possibly . Guys, one thing about spencer is shes a huge vintage girl and reporter mandy line, head of the costume department, has blax social media star. Its insane what it has done for this entire cast and crew. Its changed our life. To the better . Oh, my god, yeah, to the better. I love this stuff.
