tonight on "nightline," up in smoke. has the war on drugs failed? tonight, we go to the place where drugs are seized by the ton crossing the mexican border. and we get an exclusive look inside the top secret facility where a staggering amount of dope is stored and destroyed. twin tuition. their opponents they they have an unfair advantage, and they use it to win. they deny it. meet the pair of american twins who are the reigning tennis doubles champions. is there such a thing as twin-tuition? and, generation freedom. you say you want a revolution? the hottest youth movement on earth is saying no to deictator and no to al l eda and demanding

a better life. but what do these young muslims really want? >> announcer: from the global resources of abc news, witit terry moran, cynthia mcfadden and bill weir in new york city, this is "nightline," june 28th, 2011. >> good evening, i'm terry moran. an estimated 35,000 murders were committed in the last five years in battles over control of the u.s. market for illegal drugs. but those murders didn't happen here. they happened in mexico. meanwhile, the products keep flowing north and the cash throws south. well, tonight, we get an exclusive look at the drug war as few have ever seen it, on the border, and at a top secret facility. here's abc's peer yeah thomas. >> reporter: on a recent afternoon, "nightline" cameras were rolling as customs agents targeted this 18-wheeler. it was supposed to be carrying

furniture. but an x-ray suggested something else was hidden inside. >> wow. >> reporter: jackpot. marijuana. pay dirt. you got what you were looking for? >> we did. we found packages containing marijuana. >> reporter: in the end, the truck contained 100 ottomans filled with 2,300 pounds of marijuana. more than a ton in total. this is a major organization, a small group wouldn't be able to do something like this, right? >> that's correct. >> marijuana is the number one cash prop for the cartels in mexico. we're talking about a turf battle that is expensive and they need to have a way to finance it. >> reporter: it is the blood crop. funding armies of criminals who have fought the u.u. and mexican governments. "nightline" got unprecedented access to u.s. efforts to interdict, store and destroy the massive amounts of marijuana

being pushed northward by mexican crime lords. at the border, drug-sniffing dogs. mobile x-ray machines. special cameras to slide down gas tanks. all used to hunt for contraband. >> we find sometimes narcotics inside dashes, air condition compressors, in the rims of the tires. in the side panels, in the roof. >> reporter: what does the government do with the tons of confiscated drugs? we went to one secret facility, one of the most restricted rooms in government. we had to sign paperwork to simply go from room to room and no employee working there could be identified. stored at this vault, $59 million worth of marijuana and every other drug you can think of, captured coming in from mexico. this is about 31 pounds of black tar heroin. estimated street value? about $1 million. the drugs go north. the cash and guns flow south to

mexico in bulk. the drug lords use every tactic. submarines, tunnels, ultra light planes. the cartels areretill using men on foot to transport drugs, so-called mules. we joined up with the dea caravan transported confiscated drugs. armed guards at the wheel. so, these kinds of loads are coming in constantly. what's the story behind this one? >> the story behind this particular load, it's 320 pounds that was referred to us by border patrol. they encountered six individuals that crossed over t t river with duffel bags. >> reporter: so, exactly how at some point, the government ? has to get rid of it. the dea took us to another super secret location where the agency was in the process of destroying 50,000 pounds, 25 tons of marijuana. i know this -- i've been here awhile, there's a certain smell associated with the marijuana, too. >> oh, absolutely. it's unmistakable.

marijuana smells a certain way. not to worry. you're not going to get any highs here. >> reporter: we are not allowed to tell you where it is. and we can't identify those that work here. this place is basically a fortress. >> that's exactly what it is. what you're looking at right here is the exterior wall, which is ten inches of cement. so, nobody's goingng to be breaking in here. >> reporter: cameras are everywhere. there's so much dope to be destroyed, it has to be moved by forklift. a team of heavily armed dea agents stands by. bottom line, if the bad guys knew where this place is, they might be bold enough to come try to get it, right? >> if they tried something like that, i can assure you they would meet with some resistance. >> reporter: you're not taking any chances. >> we're not taking any chances. >> reporter: the marijuana is dumped into a large shredder before being fed into two huge incinerators. we were there in the middle of a two-week stretch destroying more

than $100 million worth of weed. >> a couple of the guys have taken to giving the inscinerato the nickname. this is dorothy right here and then we have bong 1. >> reporter: the marijuana is burned to ash and is placed in barrels. as for what's released in the air -- >> it comes out as steam. that's all it is. what you are seeing up there is safe for the environment. it's all steam. >> reporter: marijuana going up in smoke. tons destroyed but much more making its way into the u.s. for a different kind of burn. for "nightline," i'm pierre thomas at an undisclosed location, somewhere in the southwest. >> remarkable look inside the drug war there. thanks to pierre for that. just ahead, twins and doubles tennis champions who seem to know where the other one is going to hit the ball. opponents have actually cried foul, suggesting that the unfair advantage may be esp. ♪

[ male announcer ] ask your doctor about pristiq -- a prescription medicine proven to treat depression. pristiq is thought to work by affecting the levels of two chemicals in the brain -- serotonin and norepinephrine. tell your doctor right away if your depression worsens or you have unusual changes in mood, behavior, or thoughts of suicide. anti-depressants can increase suicidal thoughts and behaviors in children, teens, and young adults.

pristiq is not approved for children under 18. do not take pristiq with maois. taking pristiq with nset pain relievers, aspirin, or blood thinners may increase bleeding risk. tell your doctor about all your medications, including those for migraine, to avoid a potentially life threatening condition. pristiq may cause or worsen high blood pressure, high cholesterol, or glaucoma. tell your doctor if you have heart disease, or before you reduce or stop taking pristiq. side-effects may include nausea, dizziness and sweating. for me, pristiq is a key in helping me treat my depression. in servicing clients that serve our country. my name is marjorie reyes. i'm a chief warrant officer. i am very grateful and appreciative that quicken loans can offer service members va loans. it was very important for me to be able to close and rerenance my home quickly. i wanted to lower mymyortgage payment. quicken loans guided me through every step of the process. the whole experience was amazing!

>> announcer: "nightline" continues from new york city with terry moran. >> the ancients projected their fast nation with twins onto the stars in the sky. one of the brightest on the constellations became gemini. that's latin for twins. and the question of, what particular connection twins have and whether it truly is super natural, that still turns up in surprising places today. the tennis court, for example. here's abc's juju chang. >> reporter: they're arguably the best doubles pair ever to grace a tennis court. just watch them in action at wimbledon today. identical twins bob and mike bryan have won ten grand slams. from wimbledon to the french and

72 titles in all. >> we have the ultimate communication as twins, which is our greatest advantage. >> reporter: but is that ed advantage twin telepathy? i spent time with the bryan twins to check out the rumor that they literally read each other's minds on the court. watching them practice, you can see how similar that are strokes are. they practice likely mimic each other's moves. and look at the way they dance on the doubles court. so instinctively, in tandem, almost as a single organism with a joint brain. when you're on the court, are you aware of howowimilar your behavior is? and people talk about how you don't talk on the court. >> we do better when we don't talk. >> reporter: their opponents believe they don't have to talk, because they're communicating telepathically. >> the way they move is unlike any other team. they have this x factor. they know what the other person is going to do before they do

it. the bryan twines are exploiting an unfair advantage that's allowed them to be number one in the world for five of six years. do you think you're communicating telepathically? >> i don't think it's them pathic. being together, hanging out all the time. if you had a best friend that you hung out every day after school, that's what we have, just times that by a million. >> reporter: the bryan brothers would argue, it boils down to six hours of tennis a day, six days a week, for 20 years plus. we decided to ask their father, wayne, for the truth. do you think they read each other's minds? >> it's only because they've played thousands upon thousands of matches. >> reporter: i managed to show the bryan wroeothers a thing or two, at the men's clay court championships in houston. i'm going to join the tour any day now. they hit a losing streak this spring, so, incidentally, just

as bob got married to his long-time girlfriend. up until then, the 32-year-old bachelor shared virtually everything. their home, one car and millions in prize money. >> we had one bank account and michelle said, no, guys, it's time to split up so, we split up the real estate, it was like a monopoly deal. >> reporter: it felt like a divorce? >> kind of bickers over a couple grand here or there. >> reporter: the brothers reunited on the circuit to rekindle that twin cinergy. >> we made an effort the last five days to say, we're going to go to the gym totother. we're going to try to ramp up the twin bond. >> the closer we are, the more we're feeling it as twins. diamond of more magic that happens on the court for us. >> we wanted to put their magic touch to the test, using these cards, designed back in the '30s to test. you're going to get cards and you are going to look at the circle. when you think --

>> circle, circle, circle. >> i'm feeling a cross. >> reporter: okay. >> don't tei don't know why, bu feeling like it's a triangle. >> reporter: interesting. >> square? >> letting the twin nation down. >> you want to try it the opposite way? >> triangle. >> reporter: interesting, okay. >> one for one. >> wave. >> 100% triangle. >> tennis balls and rackets, maybe that's better. >> he's not a believer. >> reporter: bob got just 1 out of 6 correct. mike was equally unclairvoyant. and yet, their coach, dave mcpherson, says he noticed strange things that happen. a lot of people believe in this twin telepathy. have you seen that part of it? >> once or twice a year we get a twilight zone moment where they do the same thing independently,

they weren't with each other. really random stuff will happen. >> reporter: it doesn't get more random than this. when 3,000 miles apart, they go to the same store on the same day and buy the same piece of furniture. >> i got a good coauch. i texted bob a picture. earlier that same day, he was at the pottery barn in miami and bought the same couch, same color -- >> same day. >> same day. >> i didn't know he was going couch shopping. he didn't know i was. we have never been couch shopping before. >> reporter: what explains that? >> i don't know. having the same taste. living together and just seeing different -- >> >> reporter: telepathy. >> magic. >> reporter: for "nightline," i'm juju chang in texas. >> that is cool. tomorrow night, tune in for the beginning of our series, "primetime nightline," beyond belief. juju will have more of her in depth exploration of the

spring. the revolutions that have swept the middle east and changed the game right across the world. oil, terrorism. the relationship between islam and ristianity. it's all at stake. so, what forces have been unleashed there and what will happen next? that's the topic of tonight's "nightline" interview with author bruce feiler. what a year. history is hurtling ahead in the

muslim world. month after month of turmoil and upheaval, in egypt. . in libya. in syria. right across the arab world, the people are rising. and everything, it seems, is changing. >> through the moral force of nonviolence, the people of the region have achieved more change in six months than terrorists have accomplished in decades. >> reporter: but what have they accomplished? as the giddiness of those first weeks of protests fades and more sinister forces fight back, where are we? what's really going on over there? >> i think that we're seeing is these peach reaching out to us. one of my concerns, people in this country aren't in the mood to see it or hear it. >> reporter: bruce feiler spent years traveling through those lands. he's the best selling author of

"walking the bible." a soul-stirring journey of faith that was made into a pbs series. now, feiler has a new book. eneration freedom." and what he says in it just might surprise you. >> the reason i called this book "generation freedom" is because you have two-thirds of the muslim world is under 30 years old. that's a billion people in the world. consider the simple fact that 1 in 7 human beings todod is a muslim under 30. we have to get this right. >> reporter: by one estimate, the middle east will need to generate 200 million jobs by 2020. so, by sheer numbers, muslims are set to play a bigger role in world affairs than ever before. will it be hopeful or violent and chaotic? "generation freedom." that's very optimistic, people might say. >> i think what's happening is, you've got this huge population

that wants a better world. for 30 years, the chief narrative of change that they've been presented has been the fundamental. come with us, we're going to take you back to the 12th century, we're going to take you deep into islam, traditional islam and by the way, we're going to bomb and kill people who disagrgr with us. what the arab spring has provided is a rival narrative saying, better schools, freer elections. we're going to do it in the ballot box. >> reporter: a key to that transition, feiler say, religion. the very face that seemed to divide us, he argues, can bring us together. >> moses said, let my people go. we want to be free. that's a story that introduced the narrative of freedom into western civilization. founding fathers wanted to put moses on the u.s. seal.

statue of liberty was modeled on moses. the civil rights marchers quoted mo moses. one of the great, beautiful, poignant things s that freedom, the society that began in the middle east has now come back, making this attempt to save. >> reporter: it's personal for bruce feiler. after so many years spent walking the middle east, he was diagnosed with bone cancer, had his left leg completely rebuilt. when he went back this year, he climbed the pyramids. in a world full of pessimists, he is a man who seeps hope in these tumultuous times. >> we fought four wars in this region in the last ten years. we're not going to bomb our way to a solution to this problem. there has to be a new solution. and you got a choice. it's open conflict or it's coexistence. that begins with dialogue. you can't have a dialogue unless there's so
