make your guaranteed reservations right now, before it's too late. >> just a few months ago, i attended one of than merrill's training events. since then, i've sold two properties, i have six houses under construction, and i have three houses under contract. in fact, the house behind me i just sold and made $38,000. i'm providing a better life for my daughter, and i'm absolutely loving life. now i'd like to introduce you to the man who changed my life, my mentor and friend, than merrill. >> it's important for you to know that, when you attend one of my live training events, you're gonna be learning from someone who is successfully doing this right now in today's market. over the years, i've flipped hundreds of properties. i built a sizeable rental portfolio, and i have 31 deals going on right now, like the one behind me. i also have a track record for teaching other regular, everyday people how to be successful in real estate. in fact, i have some of the most

country, who have done thousands of documented deals using my system. i've literally created a road map for you to achieve your financial goals. this event -- it's gonna be a turning point for many of you watching this show right now. but you have to pick up the phone in order to make that change. all you need to do is call the number at the bottom of the screen or go online right now to reserve your two free tickets to my upcoming two-hour educational event. >> than's event gave me the confidence that i needed to succeed. since then, i have completed 15 real-estate deals, and i'm in the current process of completing two more. >> we have a lot of students who had zero real-estate experience who are now flipping multiple properties a month. however, learning how to flip is only part of what we teach you at the event. the second important step we teach you is how to build

you see, the key to building true lifelong wealth is to learn how to acquire income-producing properties, like this one right here, that produce monthly checks for you whether you work or not. and if you think about it, no matter what you do for work right now, chances are you wake up, you leave your house, you leave your family, and you trade your time for money. however, there's only so many hours in a day that you can work. so, your ability to produce income is capped. just imagine owning real estate that produces money for you every single month, regardless of whether you're at work, on vacation, or asleep in your bed. this newfound financial freedom is gonna give you peace of mind, it's gonna give you more free time, and it's gonna allow you to give back to those that you care about the most.

properties, set up passive monthly income streams, and in the next few months, i will be able to quit my job, all from what i learned. >> now, i know some of you watching at home may have been to other trainings, or you're financially comfortable right now, or you're already in real estate in some shape or fashion. you might be wondering how i can help you. well, over the years, i've helped so many people grow and literally automate what they do by learning our system. take gregg cohen, for example. gregg is a student of mine now doing over 100 deals a year and absolutely crushing it. i've even had students who have attended our training events, who started using our systems, and are now so successful that other people started taking notice, and they now have their own tv shows and have been featured on shows like "flipping san diego" on a&e and "property wars" on discovery and "house hunters" on hgtv. in fact, here is one of those students.

you teach is amazing. as you know, i was a realtor before becoming an investor, and i went to your seminar, and it all clicked. i started rehabbing properties and using your systems, and my business took off like wildfire. and as you know, the discovery channel started calling me when they found out what i was doing, and now i'm featured on "property wars." going to your seminar was the best decision i ever made. >> curt is a great guy who's become very successful using our three-step system. and what really blows me away is not only how well curt and our thousands of other students are doing financially, but, more importantly, how proud their spouses and families are of what they've done and what they've accomplished and just how happy they are now. >> i have a business that my wife and children are proud of. we're going into neighborhoods and being paid to fix up properties. i'm building a legacy for my wife, my children, and my grandchildren, and i'm doing something that i absolutely love. >> at the event -- and this is

three powerful and little-known strategies for investing in real estate passively and earning high rates of return. in fact, one of those strategies you're gonna be introduced to, you can earn up to 16% to 18% interest on your money, supported by united states state law and backed by real estate. this is a little-known, passive real-estate-investment vehicle that's been around for over 100 years. we're also gonna show you how to use this strategy and other strategies to flip properties 100% tax-free. these are killer ways to invest in real estate and possibly build a retirement account for you and your family, because your money's gonna be growing so much faster in a tax-free or a tax-deferred environment. you see, working a job and just saving money alone may not get you to your long-term financial and retirement goals, and that's

learn these powerful, long-term wealth-building strategies. >> right now, we're working on houses number 14 and 15, and we have number 16 in contract. and on our last four deals, we're averaging $100,000 in profits on each deal. >> after all the closing costs and all the expenses it took to do the rehab, we made approximately $110,000. >> this house behind me -- i got it under contract, and using the strategies that you taught me at your event, i was able to sell that contract, and i made over $9,000. >> it completely turned my life around from "a" to "z." that is, by far, the best thing that could have happened to me. >> as you're watching at home -- we only have a few seconds left, so pick up the phone and call the number right now to make your guaranteed reservation. this event is an opportunity many people will jump on in this area and change their lives forever. i really hope that you're one of

if you want a better year this year, compared to last year, you have to do and learn something different. regardless of your financial situation or your background, you can do this successfully. real estate has changed my life, and i know it can change yours. i hope today is a day that you mark on your calendar, one where you can put a mark of an event where you and your financial future and your life took a giant leap forward. thanks for watching. i look forward to having you at

now we will turn for insight to anthony salvato cbs director of elections expert on delegate math and all of the rules of the primaries and caucuses. anthony, looking forward to tomorrow, if donald trump wins florida and ohio, will his nomination be inevitable. >> he will be all but certain. he won't clinch but a commanding lead in delegates and commanding position to get the rest that he needs.

start to change the way that states give out delegates with more winner take all contests, tends to favor the leader and make it harder for trailing candidates look cruz and kasich to catch up. but more than that, trump will also be heading into a map beyond tuesday that should favor him politically. there will be contests in the northeast in the west. places that are full of the kind of blue-collar, suburban republicans voteding for him already. so the thinking will go if they can't find a way to stop him tomorrow, in places like florida, ohio, hard to see huh him at all. >> what happens tomorrow if likely now, but loses ohio? >> it will become much harder jut right. and kasich are hoping for. slow him down if not to catch him. a glimmer of hop to those who into the spring, maybe into the >> anthony salvanto, cbs news director of elections.

in a surprise move today, russian president vladamir putin declared mission accomplished in syria. and said he is ordering the withdrawal of most russian forces. since september, russian war planes have pounded opponents of syria's assad dictatorship turning the tide of the 5-year-old civil war. with russian air cover, assad's forces have captured considerable territory from the rebels. a partial cease-fire has reduced, but not eliminated the fighting. the cease-fire does not apply to isis, which still controls about a third of syria and iraq. including the city of mosul with nearly 2 million residents which has been cut off from the world since isis took over in 2014. well, tonight. holly williams has rare insight into what is happening there.

she met refugees who risked everything to escape. >> it is close to midnight on the front line just outside mosul. and these kurdish soldiers are hundreds of yards into no-man's land. so some one coming? >> yes, they are not coming. >> reporter: they're not isis fighters. but a man and a teenage girl. the man strips to his underwear to be searched. guarded by the kurdish soldiers. who fear he could be a suicide bomber. but these people have risked death to escape isis. walking for miles through the night. and they're finally allowed to cross through a trench. and into safety. and then one by one, come 12 more men. some of them handing over guns. it is an extraordinary site. very few people have managed to

water and bread. is there any sign that isis is getting weaker? >> when they first came, they were tough, said this man. but now they can see that mosul is turning against them. the men told this a plan to fight against isis themselves now they're free. and to smuggle their wives and children out of mosul as soon as they can. this was just one night on the front line. but what we heard suggested people in mosul are growing increasingly angry with isis. and scott, that could make retaking the city a little easier. when iraqi forces eventually begin their offensive to recapture mosul. >> holly nice to have you here for once where nobody is shooting. holly williams, thank you very much for a remarkable report. in a first, an american citizen fighting for isis. surrendered today in northern iraq. kurdish forces are holding him. they posted this video of him.

consideration. scott, montague has the not been criminally charged.

bob schieffer covered every presidential election since 1964. none quite like this one. what do you make of it, bob? >> scott, i will tell you on the republican side.

changing of the guard. if trump wins the nomination for the convention and looks like he probably will it is going to turn the republican party on its ear. if it goes to an open convention, it will be a bloody fight that could break the party into two parties. and in either case, republican party scott, that we used to know it, will be replaced by something new, exactly what that will be, is uncertain. and that is the scariest part of all, because the one thing that always bodes ill in politics, economics or national security matters is just that. >> do you think trump could win the presidency? >> he could. historically, nominees from outside their party mainstream do poorly when republicans split over civil rights in '64. nominated barry goldwatt r they want down to historic landslide defeat. when democrats kicked out party regulars and nominated george mcgovern in '72 he lost every state but massachusetts.

this is coming down to is basically a couple of very flawed candidates. under the old rules. but in today's politics who knows what that means or where this is going. i certainly don't. >> bob schieffer, thank you for the insight. alexander hamilton showed up at the white house today.

impunity. >> reporter: france wa molan is the head prosecutor of paris. he investigated all the big acts of terrorism here. including "charlie hebdo," the kosher supermarket, and now the november 13 attacks where 130 people were killed. more than 350 wounded. do you have phones in terrorist attacks that you have not been able to get into? because of encryption? >> yes. yes. with all these encryption software programs we can't penetrate into certain conversations. we are dealing with the gigantic black hole. a dark zone. there are so many dangerous things going on.

one of the things he is looking into is a texting app favored by isis called telegram. which like the new apple iphone offers advanced encryption. >> how often have you run in and all of your investigations into telegram. >> yes, very often. telegram. we can't penetrate. we can't get into it. >> usually people, install telegram on their phone. >> the inventer of telegram. a young man without a country. russian born. wanders in exile. he created telegram so he could communicate in complete secrecy. it has taken off, used by over 100 million people. but it is also used by terrorists now. is this a concern for you? >> definitely. 100 million users, probably this illegal activity we are discussing are only a fraction of a fraction of a fraction of the potential usage. still we are trying to prevent it. >> telegram has become a go-to site for isis. they use it to widely disseminate propaganda like this

training in syria. but isis fighters can also use telegram to send private messages to each other. to covertly plan and coordinate attacks. is there something on your site. on telegram that allows any messages. e-mails to disappear? vanish? >> yes, so in private messages we have this secret chat feature. which provides you with, self destruct timer. >> self destruct timer. >> you could set a specific amount of time. few second or a minute, or a week, up to which, after which the message would disappear. >> his obsession with secrecy and security stems from his own personal history. long before telegram, he was known as the mark zuckerberg of russia because he built a popular equivalent of facebook. in 2011. when anti-putin marches filled moscow streets.

down the organizers sites. >> and -- i refused to do that. publicly. next day i head down to policemen on my doorstep. >> wonder why? >> they tried to break into my apartment. >> there was continual pressure on him to hand over users' personal data. culminating in 2014. when under kremlin duress, he >> how long did you stay in russia after that? >> not a single day. >> o., then you fled? >> i feel that i am not welcome at that country anymore. >> that's when he created telegram. and encrypted it, he says, so activists could be assured that o government could ever access their personal data. he managed to leave russia with reported $300 million which he

telegram, costing him, he says, over a million dollars a month. >> this was something that you created to allow democracy to flourish. to allow, dissidents in russia and other countries to communicate with each other then all of a sudden you find out this terrorist group uses your site for completely different reasons. >> yeah, we were horrified. >> there is an irony there? >> there its. but you, know there is little you can do. because the if you allow this -- tool to be used for good, it, there will always be some people who misuse it. just hours after the terrorists hit paris on the night of november 13th. isis used telegram to take credit for the attacks. it was a wake-up call for

it is the first time ever in europe. that we had terrorists rampaging through our streets. first time we had terrorist thousands wearing suicide belts in heavily populated public areas. >> reporter: as head of europol he organizes information from 600 agencies. he set up a new counterterrorism center to coordinate. >> how much is encryption a problem. generally in these investigations? >> in most of them. across the -- across the tens of thousand of investigations that europol is supporting on terrorism and crime. 3/4 of them have encryption at the heart of the challenge that law enforcement face. >> what about november 13 attacks specifically. from what we see. encryption played a role in that part. that's something that we are digging into much deeper at the moment. >> why is it still a mystery. not so much a mystery.

serious investigation in public. >> we know that the ringleader of the attack. 28-year-old abdul hamid al-baljiki was a wanted fugiive. who golded authorities by bragging in the on line isis magazine how he alluded them. shuttling between europe and syria. he liked taking selfies of his exploits, often posting them online. in this gruesome video, he and his friends tie bodies to the back of a truck, abud in the driver's seat. >> we used to tow jet skis. now we tow infidels fighting us. >> what is astonishing is, you knew he was. on everybody's radar screen. i mean -- >> you are right. abud, he has been one of the major targets for france and belgium. counterterrorism for many months. >> before paris, abud was suspected of guiding jihadis in

the attempts were all foiled. in one of them, an iphone belonging to one of the jihadis was confiscated. it was not useful in finding abud because the is was encrypted. >> we have been told -- and i want to confirm it -- that the encrypted phone may have prevented you from getting information about the paris attacks. >> that is a theory that need to be looked into. to do so we really need to be able to get into that phone. you know, i say, all of these smart phones make justice blind. because they deprive us of information that can contribute to our investigation. >> see the full report on our website. cbs news.com. the overnight news will be right back. irds whistling) music introducing new k-y touch gel cr me. for massage and intimacy.

now we will turn for insight to anthony salvato cbs director of elections expert on delegate math and all of the rules of the primaries and caucuses. anthony, looking forward to tomorrow, if donald trump wins florida and ohio, will his nomination be inevitable. >> he will be all but certain. he won't clinch but a commanding lead in delegates and commanding position to get the rest that he needs. first because the rules now start to change the way that

more winner take all contests, tends to favor the leader and make it harder for trailing candidates look cruz and kasich to catch up. but more than that, trump will also be heading into a map beyond tuesday that should favor him politically. there will be contests in the northeast in the west. places that are full of the kind of blue-collar, suburban republicans voteding for him already. so the thinking will go if they can't find a way to stop him tomorrow, in places like florida, ohio, hard to see huh they suddenly find a way to stop him at all. >> what happens tomorrow if trump wins florida, as seems likely now, but loses ohio? which is possible. >> it will become much harder for him to win the nomination jut right. that's what his opponents, cruz and kasich are hoping for. slow him down if not to catch him. a glimmer of hop to those who want to see this process go on. into the spring, maybe into the summer, and to the convention. >> anthony salvanto, cbs news director of elections.

>> it is close to midnight on the front line just outside mosul. and these kurdish soldiers are hundreds of yards into no-man's land land. so some one coming? >> yes, they are not coming. >> reporter: they're not isis fighters. but a man and a teenage girl. the man strips to his underwear to be searched. guarded by the kurdish soldiers. who fear he could be a suicide bomber. but these people have risked death to escape isis. walking for miles through the night. and they're finally allowed to cross through a trench. and into safety. and then one by one, come 12 more men. some of them handing over guns. it is an extraordinary site. very few people have managed to leave mosul after isis began

stopping civilians from fleeing. and banning cell phones. overcome with relief, these men wanted to tell us why they fled. but begged us to hide their identities. to protect family members, still in mosul. these are torture marks, said this man. they heated wire and use theed it to burn me. his only crime was smoking. illegal under isis, and its harsh interpretation of islamic law. this man said he saw another mosul resident beheaded after being caught with a cell phone sim card. they caught you escape ing escaping, what would have happened? he told us three men were caught escaping just a few days ago. and isis hanged them in the street. they're a criminal gang cried this man. and we have been surviving on

is there any sign that isis is getting weaker? >> when they first came, they were tough, said this man. but now they can see that mosul is turning against them. the men told this a plan to fight against isis themselves now they're free. and to smuggle their wives and children out of mosul as soon as they can. this was just one night on the front line. but what we heard suggested people in mosul are growing increasingly angry with isis. and scott, that could make retaking the city a little easier. when iraqi forces eventually begin their offensive to recapture mosul. >> holly nice to have you here for once where nobody is shooting. holly williams, thank you very much for remark bum report. en a first, an american citizen fighting for isis. surrendered today in northern iraq. kurdish forces are holding him. they posted this video of him. he was said to be holding a

bob schieffer covered every 1964. none quite like this one. what do you make of it, bob? >> scott, i will tell you on the republican side. what we are seeing here is a

if trump wins the nomination for the convention and looks like he probably will it is going to turn the republican party on its ear. if it goes to an open convention, it will be a bloody fight that could break the party into two parties. and in either case, republican party scott, that we used to know it, will be replaced by something new, exactly what that will be, is uncertain. and that is the scariest part of all, because the one thing that always bodes ill in politics, economics or national security matters is just that. >> do you think trump could win the presidency? >> he could. historically, nominees from outside their party mainstream do poorly when republicans split over civil rights in '64. nominated barry goldwatt r they want down to historic landslide defeat. when democrats kicked out party regulars and nominated george mcgovern in '72 he lost every state but massachusetts. under the old rule, scott, what

basically a couple of very flawed candidates. under the old rules. but in today's politics who knows what that means or where this is going. i certainly don't. >> bob schieffer, thank you for the insight.
