this is the "cbs evening news." >> jeff: good evening, i'm jeff glor, after more than ten and a half years of war in afghanistan the u.s. and its allies this weekend are looking for the best way out. the setting is a nato summit in chicago against the backdrop of demonstrations. senior white house correspondent bill plante is in chicago. he begins our coverage, bill, good evening. >> good evening, jeff, well, the u.s. and its partners in nato are just plain tired of the war in afghanistan. it's unpopularity has added to political pressures here and abroad to get the troops out even sooner than planned. and the question is how o to do that without giving up the gains that have been made. that's the main topic here at the nato meeting in chicago. with france's new president saying he will pull his troops out of afghanistan by december, two year as head of the nato time line, president obama called on his fellow leaders to remain firm. >> we will stand together united in our determination to complete this mission. >> and nato

secretary-general rasmussen insisted the allies will keep their promise to day through 2014. >> there would be no rush for the exits. we will stay committed to our operation in afghanistan and see it through to a successful end. >> but the definition of a successful end to the war has changed. the nato allies now want to pull their troops back from combat and into a support role in 2013 a year earlier than they had planned. in a meeting with afghanistan's president karzai president obama acknowledged that it will still be a painful process. >> the loss of life continues in afghanistan. there will be hard days ahead. but we're confident that we are on the right track and what this nato summit reflects is that the world is behind the strategy that we've laid out. >> the president pledged that the u.s. and its ally its will continue to support afghanistan in the years after troops are fully withdrawn. but in the meantime,.

>> that the world community in particular the united states and our allies and nato, that i thought would be with us to make sure that we take, and stay. >> another difficult question, how to pay the $4 billion tab to keep coalition armed forces in place in a time of global austerity. and the toughest question of all, does withdrawing forces from nato even earlier than planned make it easier for the taliban to reassert control over parts of the country. the u.s. general in charge of the coalition made it clear today the answer is yes. he says the taliban would try to take advantage, jeff? >> bill plante in chicago. bill, thank you. whatever nato's ultimate withdrawal timetable t won't be speedy enough for the demonstrators voicing their dissent outside the summive. dean reynolds is covering that part of the story. >> reporter: thousands of protestors walked the sweltering streets of

chicago to vent their oppositions to nato and the government leaders meeting just a few hundred yards away. >> we're spending $2 billion a week killing people far away who really haven't done anything to us. >> reporter: and their chants echoed off the facades of downtown skyscrapers, a cordon of police, including swat teams marked their every foot step and lead them along their approved path. the ranks of the more violence-prone participants has been thoroughly infiltrated by undercover officers days ago, including three arrested last week who prosecutors accused of conspiracy to commit terrorism. there was also a cyberattack on the city of chicago's web site that lasted several hours. the hacker group which calls itself anonymous claimed responsibility. >> we are actively engaged in actions against the chicago police department and encourage anyone to take up the cause, the group said in a statement. >> but while some demonstrators were looking for trouble, for the most

part the protests have been peaceful. something the city's police superintendent noted amid the crowd as long chicago's lakefront. >> seeing this facilitating, peaceful process-- protest, providing for public safety wile at the same time being intolerant of crimes being committed. >> reporter: hosting the nato summit is a big deal for chicago. the city's been on edge for days hoping that the police and the protestors would be able to mingle peacefully. and so far, jeff, that does seem to be the case. >> jeff: dean reynolds, thank you. the former libyan intelligence officer convicted of the 1988 lockerbie bombing died today in tripoli. abdelbaset al-megrahi was 60. 270 people died when pan am flight 103 exploded over scotland. al-megrahi is the only person convicted. in 2009 scottish officials released him from prison on humanitarian grounds citing prostate cancer, a move that outraged many victims'

families. at the time it was said that al-megrahi had only three months to live. egyptians vote this weekend in the first free presidential election in six decades. there are 13 candidates running from all over the political spectrum. elizabeth palmer reports tonight egypt's largest minority fears their situation may go from bad to worse. >> reporter: at st. mashy's mass starts early, at 7:30. even so, the church is-- the christian ritual is an sent and familiar. but outside the door egypt now feels unwelcoming and unsafe. last may a church was set on fire in cairo, locals blamed muslims in the neighborhood. and then in october christians protesting the destruction of another church were mowed down by military vehicles. a year and a half ago millions joined the call from tahrir square for egyptian democracy.

since then and this majority muslim country, islamic politicians house flourished. so christians says father pola marqus of st. mary's now feel under siege. >> we see that in neighboring countries that islamic leaders, cristian cristiant-- christians aren't safe, he says, so we're concerned now about getting an islamist president too. egypt's presidential elections are just three days away now. and the country's christians are deeply worried. they are egypt's largest religious minority and yet they don't think that any of the candidates have made them a priority or is really capable of protecting their community. two of the front-runners in the race with a realistic chance of winning are deeply devout islamists. so christians like youssef radana don't know what to expect. >> we cannot predict exactly what is coming, will be it good, yes, but it might be worse. >> reporter: and if it does

get worse, what does the future hold for st. mary's. it's full this morning, but perhaps it won't be for long. since the start of egypt's political upheaval an estimated 100,000 christians have already left the country. jeff. >> jeff: elizabeth palmer in cairo, liz, thank you. chinese dissident chen guangcheng spent his first full day there america inside a housing complex in downtown manhattan today. with the repercussion of his arrival are being felt far beyond new york. here's tony guida. >> reporter: chen guangcheng arrived in new york to cheers and applause, after seven years of prison and house arrest, a daring escape from his rural village and more than two weeks of hospital treatment for the foot he broke escaping, chen was more than ready for the warm welcome. >> for the past seven years, he said, i have never had a day's rest, so i have come here for a bit of

recuperation in body and spirit. chen who is blind, was beaten and his family threatened for his long crusade against forced abortion. local authorities spied on him knight and day. >> the u.s. stock by its values. >> reporter: andrew nathan teaches chinese politics at columbia university. he says the chinese government acknowledged what the u.s. was insisting chen's case was about human rights. >> they didn't say this, but captively by letting go, they are acknowledging that he was abused in his local city where he fled from, and that he was fighting for people's rights. >> chen vowed he will continue the fight here but he faces many other challenges in his new world. learning english tops the list. he plans to study law here at nyu. and like any newcomer he must find a school for his two children and decide whether to stay here permanently. while he's busy with all that, chen's influence back home will suffer. >> dissident os who come out from china in the past have

pretty much lost their impact on china. they have tried to use the internet in publications and telephone and so on to maintain that works in china. but they're not really in the game in china. >> chen found relaxation today in a park near his new apartment. he has not applied for political asylum here, preserving his right to go home. but previous dissidents have been prevented from returning. and one who tried to sneak back into china was arrested and is still in prison. tony guida, cbs news, new york. >> jeff: president obama will be in missouri tomorrow to address high school graduates in joplin. tuesday marks one year since the tornado with winds over 200 miles an hour ripped 13 miles across that city. 161 people died. ben tracey is there tonight, ben, good evening. >> reporter: good evening, jeff, you know, that tornado damaged or destroyed 7500 homes in this city. so now you see a lot of this all over joplin. new houses being built.

but you also see this, painful reminders of how much destruction there was here and how much work there is still to be done. it was the foundation of where their church once stood, the members of peace lutheran came together this morning. ♪ ♪ i'm going to let it shine ♪ ♪. >> how do you feel a year later? >> oh, proud of everybody. >> the f-5 tornado that leveled one-third of joplin last year also destroyed their church. they had not yet rebuilt it but over on 26th street, the steeple of st. paul' methodist is again reaching for the same sky that last year tore it down. all over joplin new homes are building built. 446 of the 553 businesses destroyed have reopened.

the new playground in the city's main parks is a big draw. yet some things cannot be replaced. >> i just soak up the pride and the joy that my son gave me. >> reporter: michelle hare comes to this field to feel close to her son lance, this is where he died. days after the tornado she was frantically searching for her 16-year-old who was out driving her car when the tornado hit. >> his backpack was still inside of it. >> reporter: we were with her when the police came to the door. >> what happened? >> i got the news from the joplin police department notifying that my son has been identified. >> he's dead. >> yes, correct. >> but it is in some way a comfort to at least know that he is in a better place and now we don't have to wonder if he's out there needing us. >> reporter: when do you

think of him the most. >> in the morning, always in the morning. >> reporter: when you get up? >> when i get up. you do think what a wonderful soul has been lost and what a great young man. od you think about the future that he could have had. >> reporter: lance hare would have been finishing his junior year at joplin agh school. of course that high school was destroyed in the tornado. so when president obama comes to town tomorrow night to speak to the graduates, he'll be doing it at a local university, jeff. >> jeff: ben tracy, thank you. later an american ping-pong champ on her way to the olympics. a nearly complete t-rex relative goes up for the auction and the sentence of a young man against a gay rutgers university student. those for ease when the "cbs evening news" continues.

across the country, ravi was the roommate of rutgers freshman tyler clemente who committed suicide in 2010 after he was spotted during a sexual encounter with another man. raf syfacing up to ten years in prison for charges including bias intimidation which is the hate crime. he was convicted largely with his own words, statements he made on twitter and via instant message were used against him at trial. erin moriarity and 48 hours mystery has been following this case from the beginning. she joins us now, tonight. erin, its judge here has a lot of leeway tomorrow, what are we expecting? >>. >> in a word, prison. i think most legal experts don't think will get the full ten years but that he will get some. now the defense has argued no prison time at all. they say he has no criminal history. they say he has been punished enough and that what he didn't didn't involve either violence or the threat of violence but the state sees it very differently. they say he's callous and arrogant and show those remorse and they point then to this instant message that

ravi sent, one day after he learned that his roommate was missing and a probable suicide. he wrote in this message, yes, honestly, if he didn't suicide, i might be in trouble. but now they are more worried about me doing something stupid. and then ravi wrote, they don't know i love money too much to commit suicide. and that's the thing, says that shows a lack of remorse. >> jeff: so the judge is not just looking at this evidence here, he's also considering this large public debate that is going on as well, correct. >> and that usually happens with sentencing. certainly he's looking at the op eds and the letters that come to him. but most judges then look specifically what's justice in this case and for this specific defendant. >> jeff: we move beyond this specific case. if the judge does, indeed, impose a significant prison sentence, what does this is a moving forward? >> oh, i think this case has already sent a very loud message to prosecutors all through this country. because in this case a jury found him guilty of all 15 counts.

so acts that would normally be hate crimes could be charged in the future. >> jeff: erin moriarity, thank you. still ahead here, a controversial auction for a t-rex cousin. that story is next there's big news. presenting androgel 1.62%. both are used to treat men with low testosterone. androgel 1.62% is from the makers of the number one prescribed testosterone replacement therapy. it raises your testosterone levels, and... is concentrated, so you could use less gel. and with androgel 1.62%, you can save on your monthly prescription.
