For one mile of this area to be closed to traffic for all of the people there. Organizers are anticipating 25,000 of them. Of those about 600 inside the funeral home including new york city mayor bill de blasio. Police commissioner bill bratton and fbi director james comey. You are seeing pictures of some of theme arriving earlier this morning. We are hopeful we will be able to show you the Funeral Service live in the next few minutes. The funeral will be led by Buddhist Monks and will incorporate chinese traditions such as the burning of paper and money for the afterlife. A Police Ceremony will follow and then his body will be driven to a cemetery where he will be laid to rest. Liu came to the u. S. From china at the age of 12 the only child of his loving parents. He got married just this september. His widow gave this tearful statement two days after her husbands tragic death. This is a difficult time for both of our families but we will stand together and get through this together. Thank you. So lets begin our coverage by going to brooklyn where Miguel Marquez is standing by at the funeral home. Tell me where you are and what youre seeing around you. Reporter well were right outside the funeral home. I can tell you many of the officials who are meant to be here today have arrived. We have not seen the fbi director here yet, but the mayor and the Police Commissioner arrived and perhaps emblematic of how things are going for the city and for this mayor and his own police force, bill bratton, the Police Commissioner got out of his car and glad handed and spoke to many of the officers there. He is the Police Commissioner after all. These are his guys. The mayor showed up ten minutes after along with his wife. They went right into the church. Said hello, a couple nods to Police Officers as he went in, but that wasnt that warmth. There wasnt that embrace. That said at the wake yesterday when both the commissioner and the mayor walked in members of the ceremonial unit saluted both individuals as they went in to the funeral home here and now things just getting ready to get under way. We have seen other members of the ceremonial guard, presumably there will be some sort of procession down 65th avenue here in brooklyn down that incredibly impressive number of uniformed Police Officers down 65th avenue. Theyre preparing for some 25,000 Police Officers to be inside here to witness this funeral. We do not think that you will see the number of officers or perhaps any officers turn their back on the mayor as he speaks today. We expect to hear from the fbi director from the mayor, from the Police Commissioner and from the monseigneur, the police chaplain. Probably also members of the liu family will speak as well. This will go from 11 00, now, until about 1 00. Much of it though will be part of that sort of buddhist ceremony where literally they mourn, they bring food for the afterlife, they burn material goods for the afterlife and say a very very heartfelt goodbye to their loved one. Brian . Miguel thank you. Stay with us. Lets also check in with cnns sara ganim in the crowds gathered outside that funeral home. Sara from one of the live shots we were just showing, theres a sign you can see in the crowd that says god bless the nypd. But then below it also the words there in the corner of the screen now dump de blasio. Obviously this is a heart wrenchingly personal day for the family but its also it appears at least from that sign a political day. What have you seen in the crowd . Are there any other signs like that . Any other signs of this sort of protest . Reporter havent seen many signs like that brian. The signs i have seen have been in support of the officers in support specifically of officer liu and his partner officer ramos. This street filled up incredibly quickly with people who have come here but it goes back nearly a mile down this road. Police officers have lined up to watch the ceremony on jumbo screens outside. At times its raining here in brooklyn but clearly no less of a showing than was last week for officer ramos funeral despite the inclement weather. People are showing up by the thousands, not just Police Officers but also community members. We know its not just the nypd its not just new yorkers who have come here to show their support. Jetblue flew in for free more than 1,100 Police Officers from across the country. I have personally seen a variety of departments represented here. San diego, cincinnati virginia connecticut. I talked to a couple of officers who flew in thanks to jetblue from the new orleans area and one of them told me he said it was incredibly important for them to be here because not only did they like to see the showing of support from across the country for Police Officers here in new york but also they wanted to convey that they believe that the majority of the nation still stands behind Police Officers and supports them. Brian . Its notable to me youre saying you havent seen any other signs or verbal protests against the mayor or against what they believe is a sentiment against the Police Department in the city. Reporter well i didnt see that so much maybe as we expected because of what happened last week because of the turning of their backs. I didnt see as much as i would have expected. The officers i talked to specifically those who were out of town said, you know this the Political Part of this isnt something they want to get involved in. They came here to support officer liu, and they said whats going on between the 2347d and de blasio this wasnt the day for that. Tell me about what the Police Commissioner bill bratton said to the rank and file on friday. Reporter well what he said was basically a plea. He said please dont do that again. Please dont turn your backs on the mayor. Today is not a day for that. What he said was a heros funeral is not a place for grievance, its a place for grieving and he said specifically that this wasnt a mandate. No one would be disciplined over it but he asked that they not do it and the reason was because those pictures of them turning their backs on the mayor, those were very powerful pictures brian. You saw them i saw them and they really took over the narrative of the day, and that day was supposed to be about officer ramos, and it turned out it was a lot about de blasio and the nypd and he didnt want that to happen again. Brian . Sara thank you, and stay with us as this hour progresses. Now, i want to bring in several guests beginning with lee brown. He was the new york city Police Commissioner in the early 1990s. Harry see gel, a veteran reporter for the daily news. Errol lewis and tom verny, a retired new york Police Department detective. Thank you all for being here. Tom let me start with you as you see the pictures of the sea of blue again. How does it make you feel as a detired detective . I think its fantastic. The outpouring of support thats come from all corners of the united states. I believe theres even some from canada as well. It just reinforces the fact that what a tragedy this was. We started off with ramos funeral and were seeing it again today for officer lius funeral. Its not unexpected especially in an unbelievable double assassination. Its not unexpected we would have a large turnout like this and im very very happy to see so many people would come out and support the family. Are there any parallels you can recall in history to as what you said this double execution on december 20th . Certainly partners have been killed before in the line of duty. Back in if you go back into the 1970s, we had weve had officers killed in assassinations for decades. We had even back to 1988 when we had eddie burn who was killed in his patrol car. You know, the sad thing about this that people are trying to wrap their heads around these officers were not engaged in any type of confrontation, not engaged in any type of enforcement. This was just an unprovoked attack. They were sitting in their car having a roast beef sandwich and something out of left field and its something they couldnt have possibly defended themselves against. Its just the senselessness its always senseless but this level is just beyond any that i think anyone has had in recent memory. Let me turn to lee who is coming to us from houston this morning. Lee, as the commissioner about 20 years ago in the early 1990s, im interested in comparing the crime levels now versus then. Because the city has seen record low levels of crime and these funerals are going on with that backdrop. How would you compare the city during your tenure to where it is today . I became the commissioner in 1990. That was at the peak of the crack cocaine epidemic and crime was at an alltime high and my goal was to reduce crime. We did that by implementing the concept of Community Policing throughout the entire department and after one year we saw crime go down and its continued to go down ever since. Obviously the amount of crime then is still higher than it is now because of the declines weve seen in recent years, but when i went there, it was at the peak of the crack epidemic and that was one of the reasons we had such a high crime rate particularly violence on the streets. I think its worthwhile context about those low crime rates, and i know errol, you have been bringing it up on cnn earlier today. It doesnt make this any less heartbreaking, but it reminds us that the relationship between the police and the citizens they serve has evolved over the decades in new york city. It has evolved, indeed. The housing development, the Public Housing development where wenjian liu and officer ramos were on patrol has seen a 30 drop in violent crime. The Tompkins Houses had been a real problem spot just a few years prior, and they had worked it out. The local community, the local precinct they had cameras, they had foot patrols, they lit the place up at night. That turned out to be the thing that did the trick and things were really sort of coming back in the city. We can see live pictures inside the funeral home for fths irs time. We expect the service to get under way shortly. Errol, i dont want to tiptoe around this. Partly people are watching today to see if there is a repeat of that protest that we saw eight days ago with the backs turned. That of course will not be visible to the crowd inside to the speakers inside but it will be visible to us outside. What do you expect to see . I dont expect to see people pass up a chance to make a statement if they so choose and so in some ways this will be, you know as appropriate in a democracy, a chance to sort of have people weigh in. Will it be a few, a few hundred . Id be surprised if absolutely nobody wanted to make a statement. Weve seen that sign already outside. There are some who feel quite strongly that the reforms that are coming to the nypd are not to their liking. That the mayor who was implementing those reforms as the voters have basically elected him to do is also not to their liking. Theres a certain amount of conflict that you just cant get around. The question is how big, how serious, and that is what a lot of people will be and probably should be watching for. Harry, as we await the service to begin, and we will take it live as soon as we hear it begin, what do you expect to happen tomorrow . I ask about tomorrow because the mayor asked for a halt to protests against Police Excessive use of force, protests against Police Brutality after these executionstyle killings on december 20th but this is the second and final funeral today. Do you expect to see a resurgence of this Movement Later today or tomorrow among particularly young people who feel there needs to be a realignment in the relationship between the police and the people they serve . What the mayor has been hope something that asking for this timeout, which he didnt entirely get either from the Police Officers and the unions or from the protesters was a way to cool the temperature and realign and his plan from jump has been commissioner bratton was going to keep crime down and mayor de blasio was going to reform the department and hed be able to pull that off. Theres a lot of suspicious from the police and the reformsers from that arrangement and none of that goes away. This is not ending today. Lets go ahead and listen in now. The fbi director is beginning to speak. On behalf of the fbi, the department of justice, and the entire federal government. These are our most difficult days. They are days where we struggle to find meaning from tragedy, when we struggle to find words to define our loss. I was not fortunate enough to know detective liu, but i have heard many people speak of him since his loss and i know from those words that he was a person of great thoughtfulness and tremendous caring someone who cared deeply about other people which is why he became a Police Officer. There are many members of detective lius family here with us today. Although we all mourn his loss, you mourn him in a way we can never know because of the loss you have suffered and we are terribly sorry. One of the hardest things i do as fbi director is call the Police Departments around this country when an officer in that department is lost in the line of duty. I make far too many calls. 115 Police Officers were killed in this country in the last year a shocking increase from 2013. I do not know why there is so much evil and heartache in our world. I cannot understand evil. I cannot explain evil. I will not try. But what i believe with all my heart is that our obligation is to try to make something good come of tragedy so that evil is not allowed to hold the field, so that evil is not allowed to win the day. I believe our obligation is to do good. Knowing that nothing will ever make this tremendous loss somehow worth it but i believe our obligation is to try and do good to honor this good man and do everything we can to protect those who protect us. Detective liu, detective ramos, and all the men and women of Law Enforcement become members of the Law Enforcement community because they want to do good for other people. They want to rescue kids. They want to save neighborhoods. They want to make life possible ordinary life for ordinary folks. They do it knowing the danger that this work brings to them. They do it anyway. Because they understand that we make a living by what we get, but we make a life by what we give, and they have chose ton make the most remarkable lives, especially for those of us they protect. In 1985 president reagan spoke at a ceremony at ft. Campbell in kentucky in tribute to members of the 101st Airborne Division who had been killed. I want to paraphrase his words because i think he speaks to us and for us today. He said the man we mourn today was a peacemaker. He was there to protect life and preserve peace, to act as a force for stability and hope and trust. His commitment was as strong as his purpose was pure. I am honored to be here today to pay tribute to a fallen peacemaker to someone who was a force for stability and hope and trust in this great city. I hope and trust that all of us but especially dktetective lius family are able to find strength and peace. Thank you very much. And thank you, director comey. Governor cuomo was to be our next speaker here this morning but hes unable to attend due to his fathers passing and funeral viewing today. We all extend our condolences to the governor and his family. Its now my pleasure to introduce the mayor of the city of new york the honorable bill de blasio. Ery moving words. Thank you commissioner bratton. Thank you to all who have gathered here to remember this good man and support this good family. All of our city is heart broken today. Weve seen it over these last two weeks. Weve seen the pain that people feel from all walks of life a sense of appreciation for the sacrifices of this family and of the ramos family. Their understanding of people who have never worn a uniform of how many dangers our men and women in uniform face and what it means for their families. All of this city is feeling the pain right now and all of this city wants to lift up the liu family and the ramos family and always remember their sacrifice. Detective wenjian liu was a good man. He walked a path of courage, a path of sacrifice, and a path of kindness. This is who he was, and he was taken from us much too soon. Our hearts go out to his wife who married him just months before his cruel loss. To his father and his mother who have suffered the unimaginable pain of losing their only child. And to all the men and women of the new york city Police Department who served alongside detective liu these past seven years, they were his second family and that family has lost a beloved brother. For a mayor theres no more solemn ceremony than this mourning a man whose life was taken while fighting for all that is decent and good. We meet a family that has lost so much in the hospital or in their home or here at a funeral, its a reminder that what is done by good people to keep others safe and to hold our society together and just how great the dangers are. When i met detective lius family and learned more about his brave and selfless journey, i came away with a sad realization that we had lost a man who embodied our citys most cherished values. We lost in detective liu and we lost in detective ramos the very best of us everything that we as new yorkers aspire to be. We lost two individuals who were showing us the way. Detective lius story is such a powerful american story. It is such a classic new york story. A young man who came here from china with his parents at the age of 12 in search of the American Dream, in search of the dream that generations have come to new york to find. Ours is a city as proud of the statue of libe
