from nbc news world headquarters in new york, this is "nbc nightly news" with lester holt. good evening, peaceful protestors rallied in the streets of ferguson, missouri today in what police hope will be a calm tonight after a violent saturday night. a midnight curfew failed to clear the streets triggering a heavy police response including smoke and tear gas. before it was over a half dozen people were under arrest. the delicate and fast moving situation in the streets continues to outpace the investigation into the police shooting death of an unarmed 18-year-old michael brown. that probe is now working on multiple levels with the u.s. justice department stepping forward today to order it's own autopsy on brown. nbc's ron allen is on the ground in ferguson for us again tonight. ron, good evening. >> reporter: good evening to you lester. here at the command center

hundreds of police are preparing for another night of enforcing the curfew. the plan is to use as little force as possible. that was the plan last night they say until they met deadly threats. >> you must disperse the area immediately. >> reporter: last night police hit the streets ready for combat while most protesters observed the midnight curfew, a crowd of about 100 dug in. minutes later tactical units advanced firing smoke canisters and tear gas in the streets. commanders claim they faced a threatening situation including armed men on the roof top and in the street a police car fired at. and a man had just been shot. circumstances unknown. >> and, yes, i think that was the proper response tonight. maintain officer safety and public safety. >> reporter: seven people were arrested for failing to disperse. >> we stand with this family. >> reporter: across ferguson

today calls for unity and hundreds offering support to the family of michael brown, the unarmed teenager shot and killed by officer darren wilson as the photos of the officer went public. >> i'm sorry. i wear this uniform and i will stand up here and say that i'm sorry. i love you. i stand tall with you. and i'll see you out there. >> reporter: also today the justice department said it will conduct it's own autopsy. a request by the brown family hoping to show their son was surrendering when he was shot. the family already highly critical of steps taken by local officials. like the decision to release the video surveillance tape showing brown allegedly robbing a store before he was killed which many blame for igniting an outburst of violence which lead to the governor declaring a state of emergency. >> we and the security team and highway patrol didn't know it would be released and quite frankly, we disagree greatly.

>> reporter: you think the curfew is necessary? >> i do. we've had a lot of confusion. >> reporter: protestors vow to continue demonstrations. >> my constituents need to express themselves but we have to balance it off with safely. >> reporter: so far a very elusive balance ferguson has not been able to strike. missouri prosecutors confirm to nbc nus they'll begin presenting evidence to a grand jury this week. charges against officer wilson that could range from premeditated murder to no indictment at all. a process that could take several months. as they prepare for another night of curfew. thank you. with so many questions surrounding exactly what happened in that fatal encounter between michael brown and that police officer there are new calls for police officers to be equipped with body cameras. it's a measure that has support but also raises some concerns. here's nbc's mark potter. >> reporter: in the michael brown shooting the only publicly known videos were taken right

after he was shot to death, when two distinctly different accounts surfaced. police say the officer killed brown after the teen tried to take his gun but witnesses say brown's hands were in the air when the officer shot him. many believe if the officer had been wearing a camera, many questions could be answered. >> the audio-video would have potentially provided that or at least have given us a starting point to provide the rest of the information. >> reporter: more than 1,000 u.s. police departments are now equipping officers with body cameras. it's the same idea behind patrol car dash cams which gathered evidence for decades. >> body cameras create a near perfect record because they're a complete video and audio recording of the entire incident. >> reporter: in the spring of 2013, body cameras rolled as police entered a florida college dorm in search of a heavily armed student. also in daytona beach that year, when police burst into a room where they found a man holding a knife to a woman's neck. aclu supports body cameras

saying in a statement, cameras have the potential to be a win-win, helping protect the public against misconduct and at the same time, helping pro-next police against false accusations of abuse. >> reporter: but many police departments are working on guide lines and privacy. when videos can be released publicly and how to prevent selective use and editing. >> yet many found an added benefit to police cameras. >> when we are self-aware and we know we are being watched we tend to be on our best behavior. >> reporter: applying to the police and the public. mark potter, nbc news, ferguson, missouri. now overseas in iraq the u.s. launched significant new air strikes help kurdish fighters reclaim a key source of electrical generating power in that country. the mosul dam from isis militants. bill has more tonight from northern iraq. >> reporter: armed and heading for battle with the militants of

isis, kurdish fighters part of a grand force driving isis back. paving the way for them, u.s. air strikes. another 14 today. american war planes pounded isis targets clowe -- close to iraq's biggest dam. militants captured mosul dam weeks ago but officials say they have been forced to retreat. beyond this line is the main battle area. u.s. war planes firing overhead helping target the armor captured from the army. most of it originally supplied by america. >> reporter: the defense department released video of an air strike on an isis humvee and another on an armed vehicle. two of yesterday's nine attacks. older fighters believe victory is close. but isis holds huge swaths of northern iraq and outguns these likely armed men. they're appealing for heavy

weapons from america but the air strikes they say have been vital. >> very, very crucial. however, we do feel like it was slightly late, but better late than never, as they say. >> reporter: for those who fled in terror from isis attacks the fight back is welcome. these refugees are a religious minority. dozens of whom were massacred by isis two days ago after refusing to convert to islam. a baby born during their eight day escape is to be called baywar. it means no land. they have none now. they live literally on the edge of roads, of half finished buildings. tens of thousands of them. today's american air strikes against their tormenters, some small compensation for all they have lost. nbc news, iraq. let's get some perspective on the u.s. role in this.

we want to bring in kristen welker who is with the president at martha's vineyard. is this an expansion of the original mission there? >> reporter: well, lester, the administration insists the overall mission is not changing but late today the white house notified congress that the president had authorized air strikes to support the iraqi security forces fighting isis at the mosul dam. if the dam is breached, it could release a flood of water and kill thousands of iraqis and harm u.s. personnel at the embassy at baghdad. the administration says this mission is still within the goal of stem iming the humanitarian crisis and protecting u.s. interests in the area. some democrats have expressed concerns about mission creep and the expansion that could fuel that. his message to congress these military operations will be limited in their scope. he heads back to the white house for two days of meetings and then continues his vacation here on martha's vineyard on tuesday. lester. >> thanks.

talks aimed at a more lasting cease-fire in gaza continued tonight with a five-day truce set to expire again tomorrow. over 1900 palestinians and 67 israelis have been killed. stephanie gosk reports from gaza on residents anxious to get on and rebuild their lives. >> reporter: with whole neighborhoods in gaza reduced to rubble the few families that returned can do very little. they salvage unbroken cinder blocks but for now rebuilding their home is impossible. you can't find any cement, he says. even if we find it we can't afford it. cement is practically nonexistent in gaza. because israel has put strict controls how much is allowed in. now with an estimated 300,000 displaced people palestinians negotiating a long-term cease fire in cairo are making cement a priority. on the surface it may seem like a totally reasonable demand. let construction supplies in so

people here can start to try and rebuild this place. but it's become a real sticking point in cairo. like so many things in this decade-long conflict it's not that simple. the problem say israelis is that hamas uses cement and cinder blocks to make its vast network of tunnels. the israeli military says it wiped out more than 30. now it wants assurances no new tunnels will be constructed. until a deal is struck, gazans have to rely on supplies already here. so we decided to go see for ourselves. first stop, a nearby cinder block factory. is this a cinder block factory? what was the cinder block factory. they bombed the plant destroying it. they said you can't rebuild gaza until you rebuild the factories that will rebuild gaza. but maybe we can find a single bag of cement. this hardware store hasn't seen any for weeks. not even one. not even one bag. it found one bag can cost as

much as $100. way too expensive for he and his brothers who are waiting in the rubble for help. destroyed or not, they say, this is still home. stephanie gosk, nbc news gaza. a cheating scandal has shaken one of this country's most storied college football programs. notre dame prided itself on academic integrity but tonight it's searching for answers all while trying to save it's chance at a championship season. >> reporter: two weeks until kick off at notre dame stadium but the anticipation for opening day is now clouded by another scandal. >> this is not okay. you know, this is academic fraud. >> reporter: a year after their star quarterback was caught cheating on an exam, the fighting irish are forced to play without four key players including russell, one of college sports best corner backs. >> for me my emotions were shock and disappointment at the time.

>> reporter: last month a staff member caught one of the players turning in a paper that appeared to be written by another student. the university conducted an internal investigation and uncovered evidence of similar cheating by other players and several additional students. >> because of potential ncaa violations the student athletes will be held out of practice and competition until the conclusion of the ongoing investigation. >> reporter: in south bend, indiana today fans eager for another title season are now anxious about a tarnished image. >> it's unfortunate especially because the university prides itself on being very ethical and moral. >> reporter: critics say the notre dame brand, some say worth $800 million is taking a major hit. >> to have this kind of a scandal and have these national headlines coming out about notre dame, yeah, it definitely does tarnish the brand. >> reporter: the university's president meanwhile says the academic integrity process worked. >> integrity is at the heart of our mission as a university. >> reporter: the full investigation is expected to

take at least a couple of weeks. the accused students who have not commented publicly face possible expulsion as one of the most celebrated sports programs scrambles to save a season. when nightly news continues on this saturday, the face of hunger in america. it's not who you might think. and later is honesty really the best policy for the bottom line?

we've been called the land of plenty but tonight a devastating new report on hunger in america vividly reminds us that's not always the case. among the hardest hit the men and women that protect and serve this country. it's the latest in our series of reports on poverty in this nation. in plain sight.

>> reporter: in 90 degree heat you can't even see the end of the line and it's still two hours until the doors open. >> good morning, everyone. >> good morning. >> everybody's going to be happy. we have a big pantry today. >> reporter: on a weekend when enlisted moms and dads and veterans should be relaxing with their families, they're at a food pantry a mile from ft. hood. >> raisins, please. yes. >> reporter: joanne williams is an unemployed army wife and they have two children and can barely afford to spend $200 a month on food. >> if we didn't come here we wouldn't eat a lot. my kids would eat but as adults we would go without. >> reporter: this is a busier than usual saturday. because for the military, they're between paychecks right now. they'll hand out something like 10,000 pounds of food here today and that will feed as many as 1500 people. >> good morning, how are you doing? >> i'm good. >> we have to come do this just to make ends meet when it comes

to food. i don't think that's really fair. >> reporter: a report out from the charity feeding america finds 25% of active military families get and need some form of help with food. one in four households. one in five veteran families also seeks food assistance. >> our soldiers and our veterans that served our country and have been to war numerous times are coming home and not able to feed their families. >> reporter: like in west abelon, new york. >> a month supply of food. >> thank you very much. >> you're welcome. >> reporter: navy veteran and 9/11 first responder is on disability and depends on these deliveries from island harvest for his family. >> we try every month and always run short by the end of the month. >> reporter: for military families like the lewiss, it's a cruel irony. >> it would be nice if we didn't need it. >> reporter: protecting our freedom but without enough money for food it limits their own.

speaking to a group of bishops the pope said bishops don't come to asia as conquerers trying to erase national identities, instead, the catholic church wants to walk together with these nations. entering into a dialogue with countries the vatican doesn't enjoy full relationships with could help everyone. he urged the young people to bring the wisdom of the faith to every aspect of their social life and in english, a language he is clearly becoming much more comfortable with, the pope embraced the slogan of the youth day. nation youth, wake up. >> francis began the day with a poignant moment. baptizing the man that lost his son in the ferry disaster earlier this year. he took the name francis as a tribute to the pope. on monday, his final day here in seoul, the pope will celebrate mass of reconciliation for-piece for north and south korea.

north korea declined to attend. lester. ann thompson in seoul tonight. when we come back, tell the truth. how honest are you?

finally tonight we have been told that honesty is the best policy and now more and more businesses are putting that expression to the test. so are you and your fellow americans really trustworthy? nbc's jenna wolfe went in search of an honest to goodness answer. >> reporter: there's a small coffee shop in a small town in

north dakota where the coffee is self-serve and so is the bill. >> if you want something you pick it up yourself and you pay it. >> reporter: with no one behind the counter customers pay based on the gold old-fashioned honor system. >> the business plan makes sense. people have been more generous and we have been 15% over asking prices. >> reporter: honesty instilled in us from childhood is often our first virtue learned. >> the truth is inside of us. >> reporter: and the backbone of our moral code. >> all i ask for is honesty. >> we have this little voice inside our head. the little angel on one shoulder telling us to do the right thing. >> reporter: but the honor system isn't new to retail. farm stands across the country have been using it for years. circle s stand never closes. the self-serve stand had an honor box set up for years now and for the most part everyone pays. >> we found that there's still a lot of good people out there. >> reporter: there's honesty and then there's honesty. this 90-year-old has been running a self-service stand for

decades. she's all about the honor system so when asked about her surveillance camera we found, her answer was quite telling. for the last several summers honest tea has been conducting its own social experiment setting up manned kiosks in washington d.c. and allstates. >> it's what will people think of me. >> reporter: most people paid. some did not. >> you just figured it was optional? >> i mean, it's the honor system and we're on canal street so -- >> how honest of a society do you think we are? >> i think most people would definitely pay for that. >> i think it's a big world. there's a lot of dishonest people in this world. >> reporter: so we started asking around what percentage of this country do you think paid for the iced tea? >> i'd say 60 honest, 40 not. >> 80%. >> 75%.

>> about 60%. >> reporter: turns out 95% of americans were honest this year according to the company. what does that mean? obviously honesty is the best policy. jenna wolfe nbc news, new york. >> now, not to shatter your faith in mankind after that but we should mention one of the unm unmanned cameras we placed to record folks at the tea stand, you guessed it, someone swiped it. that's "nbc nightly news" for this sunday. brian williams will be here tomorrow. i'm lester holt reporting from new york. from all of us here at nbc news, good night.

we got off on lawrence expressway maybe 10:00 in the morning, we didn't get into the parking lot until 11:15. >> it may have taken awhile to get to the game. getting home was quite the breeze for many 49ers fans. the score likely played a role as well as lessons learned from the earthquake game. and the true test yet to come for the regular season. thank you for joining us. i'm peggy bunker. terry mac sweeney has the night off. it may not have been the game the levi stadium wants to stay buy. things did not go so well on the field, a lot went right off the field. team coverage of this very first football game at the new levi's stadium.
