goes to primarily how it was originally disclosed to the defense, to the police department, from the bcathe defense, and that formed a basis of my earlier motion and proceedings to get a copy of that drive. so when i originally received these training materials, for example, these training materials are 20,000 to 30,000 pages in pdf format and you can look at a pdf of a powerpoint presentation that says use of force academy, there is no frame of reference as to when it was given, who -- there is no title or dates. there is no information about who taught it, who attended this course. and some of that information contains very important statements on part of the minneapolis police department. when i received the bca drive much later and i look at them in their native formats, the reason i wasn't seeing the titles of these presentations or the dates of the presentations is because that's how they were saved on the drive into it would say 2018 phase one defensive tactics. you know now this is the training material from 2018 from the defensive tactics course. or it will say 2018 crisis inter

. >> we do have a process and that's leading on the bca to do their investigation. every shooting i have witnessed has been different. every circumstance is different. it's tragic every time, the loss of life is obviously tragic. it was important to me to get that video out and that's what i did. >> can you tell us a little bit about how long the officer was on the force here? was she around? >> the information on the officer, she's a senior officer. that's the extent that i can do. a very senior officer and i do believe the bca will be releasing all the information. they will be releasing that, that's public data. that will be coming out shortly. >> what is the normal protocol and process and how does that follow? >> there was strict adherence to the policy. when it turns into a riot. last night there were numerous to disperse because it was unlawfully assembly. it was declared five times when i was there. >> was it your decision to release teargas and to shoot rubber bullets at the young protesters? >> i'm a police chief in this city. police action is made by me.

bca agents arrested her and they say she will be booked at the hennepin county jail. that jail is about eight miles from the brooklyn center police department, the department where former officer kim potter spent the majority of her career, coming on the force back in the 90s. she now joins a list of officers across the state of minnesota charged with second degree machine -- second degree manslaughter. we are getting reaction in response to this news. activist, many of them praying and singing behind me right now said this is a step but it's not enough. they want more serious charges, specifically a murder charge. a lot of them citing the charge and incident with another officer in minneapolis that was officer missouri nor who was charged with second-degree manslaughter and a murder charge. meanwhile we are also hearing from the attorney representing the wright family. i want to read a little bit of what attorney ben crump said. while we appreciate that, no conviction can give the family their loved one back. this was no accident and it was an intentional and deliber

>> that wasn't until the bca showed up, and i believe it was special agent mike felt told me that they're going to take custody of the squad and mr. floyd's vehicle. we noticed that vehicle, or we noticed the squad car, i'm sorry, was still running so he instructed me to power it down. >> you also mentioned something about a canvas. it you at some point describe officers do a canvas for possible witnesses? >> yes. i explained that, yes. >> since you didn't know much about what it happened, what were you asking the officers to look for? >> you know, anybody that may been in the area at the time that the incident occurred. we knew that the incident occurred before we got to work, so you know, i guess we're just trying to get lucky. maybe there was somebody still there that was willing to talk to us. >> who did you send out to do the canvas? >> several officers. >> did that include -- [inaudible] >> yes, it did. >> did they locate any witnesses who were willing to speak with you? >> what was at? >> did they locate any witnesses who are willing to speak with you? >> women to speak with me? >>

i asked the bca to conduct of an investigation into the shooting and death. once completed i expect any will submit findings independent of me to the appropriate authorities, attorneys that will look and review this case. >> the and the update now is that police officer is currently on administrative leave. cnn adrian broadas live with me. it's difficult to look at bodycam video. i heard your voice in the presley conference, asking the police chief, you know, a number of questions. and it was your question that got him emotional, just speaking about the nature of his job and trying to protect his community. what did he say to you? >> you know, brooke, he said his job -- his role is to keep the community safe. and right now people who live in his community don't feel safe. you know, you could feel the pressure and the intensity in that room when the chief played that body camera footage. there were community activists inside of the room where the media was getting the update. and at the moment the officer spoke the word three times, tazer, tazer, tazer and use

so, i made that call to the bca to have them start to conduct this critical incident. >> did you then proceed to city hall? >> i should also say that i -- right after that call, i notified minneapolis mayor jacob frye to say this is the situation we have, at least right now and that i would brief him as i receive more information. i then proceeded to leave my residence and i went directly to my office in city hall. >> when you arrived at city hall, do you remember seeing any footage or video images of this event? >> the first time i saw a video of the event was after i was notified that mr. floyd had now been -- was now deceased. and so i had asked my deputy chief to pull up what i -- knowing the area really well and knowing there's usually a camera, a city-owned camera at that location, i asked him to locate that video so that i could review it. >> and that's what we would refer to as the milestone camera or milestone footage? >> that is correct. >> did you watch the footage from the milestone camera that evening? >> i did watch that. >> can you describe for the jury what you saw whe

question the jurors are going to have to decide and they're going to have to weigh the credibility of that bcae said he heard something and then he said he heard something different after that video was replayed within context. earlier in the day we also heard from multiple members of law enforcement including a use of force expert with the los angeles police department. he testified saying chauvin used excessive and deadly force. we also heard from forensic scientists or forensic experts you can say who said they found pills in the back of the police squad car with floyd's dna on those pills. so the big question is what is next? we know we are going to hear from the hennepin county medical examiner. we should hear from the medical examiner later this week and the medical examiner will be able to talk about the autopsy and the cause of death. back to you. >> adrian, thank you so much for your coverage on this. appreciate it. >>> the biden administration now reviewing more than 5,600 new files to determine whether more children were separated from their families at the u.s./mexico border than p

this particular case was limited to a couple hours of time making sure those things were done until bca agents arrived and you handed off the scene. >> yes, that's correct. >> it was not until later you were asked to review the body worn camera of the officers and consider the use of force. >> yes. >> it would not be within your normal role or job duties to do such a use of force analysis, right? >> that's correct. >> i have no further questions. >> redirect? >> lieutenant zimmerman, you had an opportunity to review the body cameras worn by the officers? >> yes. >> did that capture the bystanders? >> yes. >> was there something about that group of bystanders that they were an uncontrollable threat to the officers at the scene? >> no. >> let me ask it this way. would there be other ways for officers to deal with bystanders? >> yes. >> could that include calling for backup? >> yes. >> would the presence of multiple officers at a scene be a relevant fact for an officer to consider when using an amount of force on a handcuffed and restrained subject? >> no. it shouldn't be. >> but if there

so i made that call to the bca to have them start to conduct this critical incident. >> did you then proceed to city hall? >> i should also say that i -- right after that call i notified minneapolis mayor jacob frye to say this is a situation that we have at least right now, and i would brief him as i received more information. i then proceeded to leave my residence, and i went directly to my office in city hall. >> when you arrived at city hall, do you recall seeing any video images or footage of this event? >> the first time that i saw a video of the event was after i was notified that mr. floyd had now been -- was now deceased. and so i'd asked my deputy chief to pull up what i -- knowing the area really well and knowing that there's usually a camera, a city-owned camera at that location, i asked him to locate that video so that i could review it. >> okay. and that's what we would refer to as the milestone camera or milestone footage? >> that is correct. >> okay. did you watch the footage from the milestone camera that evening? >> i did watch. >> can you describe for the jury what

meanwhile, so many have asked how did potter make this missnake a bca investigator took a look at potter's duty belt and discovered her handgun was hole ste already stered on the right side and the taser in the left and the taser was in a position that would require potter to full with her left hand, and on that day we learned she was training rookie officers. wolf. >> stand by. we'll get back to you. right now i want to get the latest on the recall another police officer who is on trial for murder in the death of george floyd. our senior national correspondent sara sidner is covering derek chauvin's trial for us. sara, chauvin's lawyers are trying to cast doubt on how george floyd died. tell us what happened today. >> reporter: yeah. we heard from a former medical examiner who testified for the defense who basically said it a several things killed george floyd but not one of them with the officers on him or chauvin kneeling down on his neck. >> there are multiple -- multiple entities all acting together and adding to each other and taking away from a different part of the ability to get o
