and what we have done is to ask leading scholars in america. , describing what they agree n disagree about. in what the scholars agree about it is day bipartisan statement is a unanimous supreme court majority opinion. we're building on to it but let's begin with the fifth amendment that includes the due process clause nobody should be deprived of life or liberty without due process. click on the common statement you'll see two leading scholars telling you fifth principles that government should be limited how it makes decisions in the magnet korda -- the magnetic card at hand chapter 39 no free man shall be arrested or imprisoned and this legal age comes from due process. how exciting and ended the development of the due process clause and then you can read the the disagreement how this amendment should apply to face with his say my fifth introduction but that's not all but only kiddy by a knife.

what we have done with the help of our great partners is to ask the leading scholars in america from every perspective, liberal and conservative and everywhere in between to write about every clause of the constitution describing both what they agree about and what they disagree about so when you go to the site you can be confident that when you read the common statement about what scholars agree about this is a bulletproof bipartisan statement in which scholars with greatest divergent perspectives agree like unanimous supreme court majority opinion. and then you can read their separate statements which are like separate occurrences. bill of rights day, here we have only the first week in amendments to the bill of rights but now all 15 amendments building up the rest of it over the next few years. let's begin with the fifth amendment which says a whole lot of things but it includes what is called the due process clause which says no person shall be deprived of life, liberty or property without due process. what is the core meaning or historic source of that? you can click on the comm

almost all legal scholars say yes, certainly. but now senator john mccain, who faced a similar issue during his 2008 bid says he is not so sure. >> what came up in my race because i was born in panama, but i was born in the canal zone, which is a territory. it's a u.s. military base. that's different from being born on foreign soil, so i think there is a question. i am not a constitutional scholar on that, but i think it's worth looking into. i don't think it's illegitimate to look into it. >> the flames on this issue, if you will, have been fanned all week by donald trump, who now tells wolf blitzer that cruz should go before a judge to settle this issue. >> he should ask for a declaratory judgment because that will clear it all up. this would clear it up. you go into court, you clear it up. declaratory judgment. the judge would rule. once the judge rules he's okay, then the democrats can't bring a lawsuit later. >> i want to go to cnn's chief political correspondent, dana bash. she is with the cruz campaign in storm lake, iowa.

law professors will remain traditional not critical legal scholars.their influence has been probably felt in the legal academy and therefore has been influential in undermining commitment to the role of law. as it turns out, the rule of law maintains a continuous foothold on an important concept of the legal academy. it means something different. it's not the classic love neutrality and so forth,. if the government wants to do something in his to come up with a non- ridiculous theory why it's legal. so this is him but no constraints on the government because the law will only been so far without breaking, it just doesn't put much of a constraint on the government. in fact, if you're thinking to yourself what has the obama administration really wanted to do that they decided not to do because someone said it was illegal to do so, the list is not very long. when the bush administration pushed executive power to his limits and beyond there were a few lawyers who objected both internally and summary threatened to resign if the administration went where wa

clearly there are both legal scholars and others who think this is, perhaps, a legitimate issue. my issue is that i think both donald trump and ted cruzhg are far too divisive as candidates to ever beat hillary clinton. i'm a conservative who can beat hillary clinton who won't sacrifice our

and an distinguish scholar and a great institution. as we begin to wind down, the role of academics, as a scholar you have an opportunity to talk to an audience of young people all the time. but the young people that you talk to represent an important segment but a narrow segment. what is the role in the revolution of values of those in the academy versus those who or what i call on the practical side? >> guest: beauty of a liberal arts education is this, it creates the condition for us to engage in that arduous task of continuing to grow. of tough questioning. part of the ugliness about politics and folks are so certain about everything, they dug in their heels. but what are the things about what i do that are so wonderful is the very way in which it forces us, it forces us to engage in itself inventory. to reach for broader horizons, to reach for more expansive conception of who we take ourselves to be. one of the beautiful things going back to how we started about morehouse is that i was able to be about four or five different peopl

most law professors were or remained traditional scholars. influence has been broadly felt and therefore has been influential in undermining commitment to rule of law. rule of law maintains a tenuous foothold in the liberal legal academy, but it means something different. the neutrality and so forth but it has to come up with a non- ridiculous. this doesn't know constrictions because the law only been so far without breaking. and in fact if you are thinking to yourself with thing as the obama administration wanted to do that it has not done, even though there have been so many legal controversies. also when the bush administration pushed executive power there were quite a few lawyers who objected. and then bush pushed back. shirley the most andhave been someone in the administration who should have been doing this. i did not see a single example. go ahead and do this. admittedly government officials stretching their power as far as they can, as i mentioned at the beginning of my talk obama asis the 1st one to brag about going around congress

senator john mccain and constitutional scholars are now involved. " cruz's citizenship. today, more questions about ted cruz's legal right to run for president...the texas senator...born in canada to an american mother. sot ted cruz " as a legal matter the question is straightforward and settled law that the child of a us citizen born abroad is a natural born citizen." the man raising the concerns...his fellow republican donald trump. he told cnn cruz should go to court. sot donald trump "ted, he should ask for a declaratory judgment because that would clear it all up. i'm doing this for the good of ted." cruz on the stump in iowa called it all...noise. sot ted cruz my focus is on addressing the real challenges and issues facing the american people cruz has pointed to 2008 presidential contender john mccain who was born in panama. but mccain told the chris merrill show he was delivered on a us base. and as for cruz: sot john mccain audio i think there is a question. i'm not a think it's worth looking into abc news did ask the constitutional legal scholars who say it appe

legal scholars who say it appears cruz is in the clear but the issue is still unresolved. sot josh earnestwhite house press secretary seven or eight years of drama around the president's birth certificate, if republican primary voters were to choose senator cruz as their nominee cruz renounced his canadian citizenship 18 months ago. this morning, donald trump tweeted that was a wise move by cruz. kenneth moton, abc news washington and speaking of trump... he will be at the reno ballroom on center street on sunday afternoon. the rally starts at 1 p- m, doors open at 11 o'clock. ohio governor john kasich will also be makign a stop in northern nevada. he is holding a meet and greet at the washoe county g-o-p headquarters next tuesday at 1:45 p-m. both events are open to the public, but an r-s-v-p is requested. democratic presidential hopefuls gathered in las vegas last night for the first caucus dinner in the west. at the dinner, hilliary clinton promised if she becomes president, nevada will quote "always have a friend in the white house." bernie sanders and martin o'malley

all scholars say he is a natural born citizen. he meets the constitutional rierpt. so why is donald trump stirring the pot? why now? >> just trying to raise questions in the minds of those iowa cote voters out there. we are getting closer and closer to caucus time in iwest virginia that's where ted cruz is doing his best work. that's where he is rising in the polls. i think donald trump is trying to lay the groundwork of doubt as much as he can with, you know, with those voters. he also talked about cruz' religion a little earlier, mentioning he has deep roots in cuba. trying to make cruz sort of this other candidate in cuba, not iwest virginia i think it's probably a little of what's behind this. >> it's interesting, john mccain was not born in this country. it didn't raise any kind of legal questions when he was running for office. so you wonder how long or the legs of this line of criticism from donald trump has? >> you see, donald trump said the, you know, cruz running would put republicans in a precarious position. braermd, broward county obama and hillary clin

legal scholars say he meets the requirements. also interesting to see, jeremy, how josh earnest talked about this at the white house yesterday. >> it would be ironic if after seven or eight years after the drama of the president's birth certificate if republican primary voters were to choose senator cruz as their nominee, somebody who actually wasn't born in the united states and only 18 months ago, renounced his canadian citizenship. >> stirring the pot as much as he humanly can. >> this is the thing that gets democrats licking their chops. for so long, you know, it is the same voters that support ted cruz, the tea party voters, who questioned president obama's citizenship. not just question his citizenship on the grounds that say his mother wasn't american. president obama's mother was. they were questioning that obama was born on foreign soil in kenya, specifically. president obama since released his birth certificate and showed he was born in hawaii. there are lingering questions. the people who support trump and people who s

this turns out to be more complicated that some scholars think. to the extent that one can ever make headlines about the 19th century history perhaps tonight , i can break a little scholarly news on c-span. maybe. historian michael ross, who i told you was all he sitting here in the second row, deserves much of the credit for uncovering the role that race plays in the slaughterhouse cases. in his biography of justice miller, he made a powerful case that the constitutional challenge of the slaughterhouse act was racially motivated. the louisiana legislature that passed the law was a biracial legislature dominated by republicans. the house was comprised of 65 republicans, 35 of which were black to 36 democrats. the senate held 23 republicans, seven of which were black, 13 democrats. was a product of a new state constitution that the segregated education, prohibited racial segregation in public places and denied former confederates the right to vote. it also included a bill of rights the first in louisiana , history that voided the black codes, outla

i think the scholars show that as well. in order for the two sides to move up, we have tried very hard to accommodate the chinese ideas in order for the negotiations to move on. it is also necessary for the chinese side to move forward as well. during the campaign. , we noticed the chinese side being reserved in statements and actions. i think that is a positive step forward. i am sure there will be more opportunities for us to send goodwill to the chinese side. i hope the chinese side can respond in a reciprocal manner so the negotiations can move on. the trust will be built step-by-step. important.nsensus is i hope i do not have to read it again, but it is very and it has been stated during the campaign. realizese chinese side the goodwill coming from the dpp side. start, especially when the dpp comes into office this year. >> you keep calling her the chairperson, but she is now president elect. >> thank you for the reminder. >> let me ask you a question the south china sea, which is on the minds of many people. we expect

you will find that the overwhelming -- overwhelming response of american scholars, civil rights workersand i hope to count myself as one, a person interested to solve this one great wrong of american life is that this report is accurate, compassionate and useful. the question is what to do about the problems that it raises. >> you start the report by saying the u.s. is approaching a new crisis in race relations. what do you mean a new crisis? >> last winter, i felt that the great crises having to do with the protection of the liberties of negro americans in the south were probably coming to -- coming to an end. we were going to get this work done. the majority existed in the american people believed it should be done. it seemed to me we would turn to the problem of the northern ghettos where just passing a law was not going to change takes. problems were much more difficult and less responsive to feeling that you had to do hard, difficult to slow things. i felt this would inevitably cause frustration anger and disappointment. >> one of the major conclusions you come to is that the negro

for decades many scholars of policing and policing them self believe law enforcement had little impact on crime rates. venerable police scholar david bailey, who several in this room actually know well and have worked with, summed up this view nicely in his 1994 book police for the future and i'm going to quote. the police do not prevent crime. that is one of the best kept secrets of modern life. experts know it. the police know it. but the public does not know it. yet police pretend they are society's best defense against crime and continually agree that if they're given more resources, especially personnel, they will be able to protect communities against crime. this is a myth. now today, of course, police executives are expected and expect themselves to reduce crime in their jurisdictions. policing's potential to impact crime rates is conventional wisdom, actually, thanks in large part to the work of folks in this room like david wiseburg, frank zimmering, sitting right next to david, thank you. and other folks like steve levitt, who some of you know. however, as my colleague tom ty
