along with spencer ackerman. been discussing the turn of events in which dzhokar tsarnaev has been apprehended by police and is now in custody. he's in a hospital being treated for wounds sustained in the gurn fight with police in the wee hours of this morning. it's been a truly remarkable 30 hours in this case. exhilarating and terrifying at times and deeply saddening with the loss of the life of an m.i.t. police officer. let's talk through what has been a very confuse iing chain of evs and what we know with the release of photos and the suspects in the boston marathon bombing. this is what happened. those photos released at 5:20 yesterday evening. suspect number one and suspect number two. they asked the public for help in identifying them and tracking them down. that was 5:20 p.m. yesterday. by 7:08 nbc's pete williams was reporting that the fbi was getting calls from people claiming to know the identity of the suspects. at 7:18 someone posted this high resolution photo to an online running forum that appeared

. >>> some truly great reporting from spencer ackerman who was on the show last night. he got an exclusive interview with an american-born jihadi. he agreed to speak from direct messages on twitter and said i believe in attacking u.s. interests everywhere, no second thoughts or turning back. he writes sentences like that make it likely hamady will be the next american killed in the next drone strike. a terrific read and character study. worth checking out. there's been an online brewing on the subject of marriage. 20 something should take the plunge and follow her lead and get married young and another says it's best to wait and matthew sifting through and armed with charts, he has data from the national marriage project in "knot yet," makes the case waiting to get hitched causes women's earnings to go up. money is not happiness and it is complicated. self-reported happiness for one's marriage is highest for those who marry in their mid 20s compared to those 2 do it in late teens or late 20s? should you say i do? it depends what you want out of marriage, a career and li

. >> sue terry, spencer ackerman, mattie duppler, that is "all in" for this evening. rachel, sorry i'm throwing it to you late, but i know how much you love defense overruns. >> if you're going to be five seconds late because we have to learn that our cost overruns alone are the third largest defense budget in the world and we learn it from spencer, i'm with you. >> awesome. >> thank you, awesome. thanks to you at home, as well, for staying with us this hour. the president of the united states, flying about the country and making public appearances, that is always kind of the fulcrum around which the rest of the day's political news tilts. that was largely true today with the president in colorado and then heading to california. but there was also big substantiative news today from the new secretary of defense, from chuck hagel, who gave the first big policy speech of his time in office. chuck hagel talked about the military being an essential tool of american power, but one that must only be used with a keen appreciation of its limits. that kind of talk drives nuts a

reading into the record, responsible reporting from people like spencer ackerman and noah shackman who've done great reporting on this. commentary from people that have gone to the heart of what this issue is about, extrajudicial killing. reading that stuff into the record, 1that was the first tim we've talked about in this country on the floor of the senate the killing of anwr awlaki's 16-year-old son. 33% was sane. the rest was this crazy tea party carnival full of just nuttiness and extraneous stuff no one actually takes seriously. it does a disservice that we don't have serious politicians in this country willing to have a spine on this issue and ask the right questions. we had the first hearing on drones in the senate yesterday. a first time a yemenese civilian testified on the floor of the u.s. senate. we need more of that. we need to listen to the people on the other side of the missile. we need congress people with spine in this country and not just leave it to a random guy like rand paul to stand up and be the only guy talks about this. quite frankly i don't find him credible on
