this is the "cbs evening news" with scott pelley. >> pelley: it's wall street's worst start to a new year ever. one market expert put it bluntly today-- investors are scared to death. as oil prices fell to levels not seen in more than a decade, investors dumped stock, and at one point, the dow was off more than 500 points. at the close, it was down 390, putting the index below 16,000. senior national security correspondent-- senior national correspondent, i should say, anthony mason is joining us now. anthony, what's going on? >> reporter: all three major indexes, scott, are now in correction territory. that's down 11% or more from their recent highs, as worries about global growth have spread, stocks around the world have lost $5.7 trillion in value just this year. oil prices are worrying wall

crude, which fell to $29 a barrel, a 12-year low, is down more than 70% over the past 18 months. there's just too much oil. the world is using 95 million barrels a day but suppliers are pumping nearly 97 million, and if sanctions on iran are lifted, more oil will flood onto the market. that's good news for gas prices. a gallon of unleaded has dropped to $1.92, almost half what it was 18 months ago. and there's no floor in sight for oil prices yet, or for this market. even strong jobs numbers last week couldn't put the brakes on this slide, and no one is sure what will. >> pelley: this is all reminiscent of 2008 when the markets crashed and froze up. any chance that we're headed in the same direction? >> reporter: i don't think so, scott. that was sparked by a financial crisis. the underlying u.s. economy is strong, but there are growing concerns that a slowdown in china might spread globally, even to the u.s., and stocks are likely to remain skiddish until oil prices stabilize. >> pelley: and banks are in much better shape than they were back

anthony, thanks very much. you might have thought this economy would have dominated last night's republican debate, but instead the leading candidates took stock of each other. ted cruz showed that he hadn't forgotten what he learned as a student on princeton's debate team. there were seven podiums, but often it seemed just two contenders. 17 days to iowa, and here's major garrett. >> this is actually a movement. >> reporter: donald trump rallied supporters outside des moines today after an overnight flight from south carolina. >> zero sleep. i mean, zero. >> i recognize that donald is dismayed that his poll numbers are falling in iowa. >> as you know, ted, in the last three polls, i'm beating you. >> reporter: trump and cruz broke what had been near- fraternal bonds to spar over cruz's birth in canada to an american mother. >> you have great constitutional and you know-- i'm not bringing a suit. i promise. but the democrats are going to bring a lawsuit.

defending the constitution before the u.s. supreme court, and i'll tell you, i'm not going to be taking legal advice from donald trump. >> you don't have to. take it from laurence tribe. >> reporter: then marco rubio weighed in. >> i hate to interrupt this episode of "court tv." >> reporter: for vast stretches of time, trump and cruz dominated as when trump took offense to cruz's description of his hometown. >> everyone understands that the values in new york city are socially liberal, pro abortion, pro gay marriage, focus around money and the media. >> when the world trade center came down, i saw something that no place on earth could have handled more beautifully, more humanely than new york. >> reporter: cruz, whose base is social conservatives, today apologized, but not to trump. >> i apologize to all the pro life and pro marriage and pro second amendment new yorkers. >> reporter: clinton saying it was just this once, praised trump's defense of the big

scott, jeb bush picked up the endorsement of south carolina senator lindsey graham today, a move that brings almost no money and very few grass-roots supporters. >> pelley: major garrett on the campaign for us. major, thank you. and please note that john dickerson's campaign coverage this sunday on "face the nation" will include interviews with democrats hillary clinton and bernie sanders. in hawaii tonight, the search continues for 12 crew members after two marine corps helicopters collided overnight off the island of oahu. john blackstone is following this. >> reporter: high surf and rain off the north shore of oahu has added to the challenge for search-and-rescue teams looking for any signs of survivors amidst the debris of the crash. captain timothy irish: >> there are 12 marines that are still missing. their whereabouts are unknown. we're still looking for survivors.

called super stallions, are some of the largest helicopters used by the military. capable of lifting heavy cargo loads and carrying more than 50 fully equipped combat troops. marines gathered along the beach, joining the search near the surfing town of haleiwa. six crew members were aboard each of the two helicopters that collided during a routine training exercise late last night. around the time j.k. hanoa heard an explosion. >> and then i heard another one shortly after. it was kind of spontaneous-- boom! and then another boom! >> reporter: a coast guard helicopter spotted debris about two and a half miles offshore. two navy destroyers joined the search for survivors, along with rescuers from the air force and honolulu police and fire departments. searchers say debris from the crash may wash up on oahu's north shore beaches. scott, they were asking the public not to pick up anything that comes ashore. >> pelley: john blackstone reporting tonight. thank you, john.

michigan, tonight, where the city switched water sources to save money, only to tap into a sea of trouble. the governor is asking president obama to declare flint a disaster area, but residents say the governor is the disaster. adriana diaz is there. [chanting] >> reporter: flint residents stormed the state capital this week, calling for the resignation of the governor after learning their drinking water was contaminated with lead. >> right now, what we're looking for is accountability. >> reporter: the problems began after the city switched its water supply to the flint river in the spring of 2014. the corrosive water stripped lead from pipes, and children in the city were found with high levels of lead in their blood. the city has changed its water source, but environmentalists say the water coming out of faucets is still unsafe. this week, the national guard started distributing bottled

now health officials are investigating a spike in legionnaires disease. there have been 87 cases of the pneumonia-like disease since the water switch and 10 people have died, including troy kidd's mother debbie who died in august. >> so did she die because of somebody didn't want to say, "hey, the water might be bad" that's my question. >> this is what was coming out of their tap. >> reporter: dr. marc edwards of virginia tech has been studying flint's water. >> if, indeed, it is true this can be linked to the water system-- and there's a pretty strong likelihood that it is and that it will be-- yes, unfortunately, people will have died from this disease. >> reporter: fema says they'll respond to the governor's emergency request as early as this weekend. scott, the move would unlock federal funds to repair flint's water system and help residents. >> pelley: adriana diaz in flint

adriana, thanks. there was a terror attack tonight in burkino faso, a muslim nation in west africa. gunmen stormed an upscale hotel frequented by westerners. a number of people have been killed. hostages were taken. an islamic terror group affiliated with al qaeda has claimed responsibility. europe is rethinking its refugee policy after more than a million refugees settled there last year. the refugees fled wars and poverty in the middle east and north africa, but new arrivals in greece are finding europe's welcome has limits. holly williams has that. >> reporter: despite the freezing cold, the rough seas, and the risk of drowning, the migrants keep coming. more than 1,000 people arrive in greece every day, but now

thin. farshad rahimi fard told us he left iran in search of religious freedom, paying a smuggler nearly $3,000. but he's now stranded in greece, living in this abandoned hockey stadium and could face deportation after he, like thousands of others, was turned back by macedonian border guards on the route to germany. >> reporter: hundreds of other stranded migrants, many from north africa, are being held under lock and key in this greek detention center. we were denied permission to go inside, but one of the inmate sent us these videos showing the conditions, including a protest that he said was put down with tear gas.

built razor wire fences. others will now only accept refugees from syria, iraq, and afghanistan. as an iranian, farshad can go no further than greece, destroying his dreams of a new life in europe. >> reporter: most of the migrants arriving in europe set off in boats from turkey, and last year, europe promised to pay turkey around $3 billion in return for its help stemming the flow of people. but so far, scott, that's had very little effect. >> pelley: holly williams in istanbul for us tonight. holly, thank you. it was 25 years ago this weekend that u.s. bombs first fell on baghdad. operation desert storm wrapped

forces gave up kuwait. david martin now on the lessons of that war. >> reporter: in retrospect, the first gulf war seemed so simple, starting with this definitive statement from president george h.w. bush four days after saddam hussein invaded kuwait. >> this will not stand, this aggression against kuwait. >> reporter: after a buildup of 500,000 american troops in saudi arabia, president bush issued the execute order that turned into one of the most lopsided victories in military history. >> i was able to guarantee president bush that we would succeed because the iraqi army was sitting there in kuwait like a golf ball on top of a tee waiting to be hit. >> reporter: colin powell was the chairman of the joint chiefs at the time and described the war plan in unforgettable terms. >> our strategy in going after this army is very simple. first we're going to cut it off and then we're going to kill it. >> reporter: is it ever going to be that simple again? >> i don't think it is.

it's not a single guy with an army that's easy to defeat. >> reporter: do you think desert expectations about what military >> it may have in the mind of some. it didn't in my mind. i understood the nature of that war, how limited it was, and it wasn't a model of what we can do in every other conflict that comes along. >> reporter: victory in the desert was followed by parades, but a new biography of president bush quotes his diary as saying, "i have no elation." >> we had hoped after desert storm saddam would be so weakened he would be taken down or he would quit. that didn't happen and that was a great disappointment to president bush. >> reporter: but at least the president said the united states military had finally risen from the ashes of vietnam. it could fight and win a war overseas. >> by god, we've kicked vietnam syndrome once and for all. thank you very, this much. >> reporter: president bush mused to his diary that desert storm might help establish a new

think that goes a long way but again, i'm not sure we're there yet. >> reporter: chipotle's health-related issues began last july with a small e. coli outbreak in seattle. in august, 200 people were sickened by norovirus in california. in october, dozens of customers in chipotle restaurants across nine states came down with e. coli infections, and the chain temporarily closed 43 of its restaurants. the company is now tightening its food safety procedures, including doing d.n.a.-based tests on ingredients before they're shipped to restaurants and beefing up worker training. >> there's a lot of talk, but we haven't seen the data and the behavior change. we need to see that changes have been made. >> reporter: well, chipotle's stock price rose almost 20 points after today's announcement, but, scott, that's far below where it had been trading. >> pelley: anna, thanks very much. the sean penn interview next.

why you wanted to go there. second i wanted to know the sense of how you felt about the risk you might be taking and why that risk was worth it. >> i only had i thought that this is somebody who upon-- upon whose interview could i begin a conversation about the policy of the war on drugs. that was my simple idea. >> reporter: you have no regrets? >> yeah, i do-- i have a terrible regret. >> reporter: what are the regrets? >> i have a regret that the entire discussion about this article ignores its purpose, which was to try to contribute to this discussion about the policy in the war on drugs. >> pelley: charlie's interview with sean penn this sunday on "60 minutes."

come on in pop pop. happy birthday. i just had a heart attack... and now i have a choice. for her. for them. and him. a choice to take brilinta. a prescription for people who've been hospitalized for a heart attack. i take brilinta with a baby aspirin ...no more than 100 mg. as it affects how well it works. it's such an important thing to do to help protect against another heart attack. brilinta worked better than plavix. and even reduced the chances of dying from another one. don't stop taking brilinta without talking to doctor. since stopping it too soon increases your risk of clots in your stent, heart attack, stroke, and even death. brilinta may cause bruising or bleeding more easily or serious, sometimes fatal bleeding. don't take brilinta if you have bleeding, like stomach ulcers. a history of bleeding in the brain, or severe liver problems. tell your doctor about bleeding, new or unexpected shortness of breath, any planned surgery and all medicines you take. i will take brilinta today. tomorrow. and every day for as long as my doctor tells me.

a german shepherd named jethro. he was more than just a police dog. the davis family got jethro at eight weeks. he grew up as both a family pet and a k-9 officer. every day, seamlessly transitioning from pillow to police work and back again. until last weekend. when he charged at that burglar >> i'm here because he did what he did. >> reporter: ryan says the dog saved his life, but remarkably, he says he wishes it was the other way around. >> i would trade places with him in a heartbeat. >> reporter: do you mean that? >> absolutely. because i wouldn't have to sit here and suffer over the loss of him. he's left a hole that will never be filled. he gave his life for me.

>> reporter: it's hard to imagine owing such a debt with no way to pay it back. but this week, the city of canton tried. they filled their civic center, invited police officers from across the country, and honored jethro on what would have been his third birthday. and as for the killer, police do have a suspect in custody, but that's of little consolation to ryan who says the only thing that will make this better is making certain his partner is never forgotten. so how do you want him remembered? >> the one word that comes to mind is "unconditional." he was unconditionally loyal, loving, supportive. he was-- he was a hero. >> reporter: he was a hero, as is any officer who can be this devoted. steve hartman, "on the road," in canton, ohio.
