universally accepted active shooter protocols. they allowed the gunman to remain in the classroom for more than 70 minutes. there were children still alive inside, one of whom repeatedly called 911 for help. there were wounded teachers fighting for their lives. tonight we take a close look at the false and at times misleading information initially provided by texas law enforcement and public officials to families and reporters about the police response. throughout this hour, we are being careful about what body camera and surveillance videos we show you. there will be no images of violence or sounds of gunfire. we want to be respectful of all those grieving in uvalde. some of the videos though are difficult to watch given what we know was happening elsewhere on screen. there's still a lot to learn, but it's worth mentioning had parents and families, reporters and others not demanded answered from law enforcement officials in the hours and the days and months after this massacre, it's likely we wouldn't know nearly as much as we do about what really happened in uvalde. >> breaking news out of texas for you now. police on the scene of a deadly shooting at an elementary school in texas. >> the awful images coming in from robb elementary school about 80 miles from san antonio. >> for hours after the shootings in uvalde, there is chaos around the school and few details released to the public about the police response. >> we've not been given or heard any reporting on any exact timeline. >> is it clear to you how quickly police were able to get on the scene? >> it sounds like it was relatively quickly, but obviously not fast enough to prevent what has happened here. i don't want to go beyond that really. >> sure. >> because we haven't really gotten any indication as to exactly how quickly agents were able to respond to that scene. >> there's a lot of facts that we just don't know here. >> i think right now it's important that we wait until we started getting official comments being made so that we really are basing it on facts. >> the best information that we have at this time understanding very importantly that this is an ongoing investigation and ongoing investigations often reveal new information. >> some 24 hours after the shooting, texas governor greg abbott, senator ted cruz and other state officials and law enforcement personnel hold a press conference. >> as horrible as what happened, it could have been worse. the reason it was not worse is because law enforcement officials did what they do. they showed amazing courage by running toward gunfire for the singular purpose of trying to save lives. it is a fact that because of their quick response getting on the scenes, being table respond to the gunman and eliminate the gunman, they were able to save lives. >> the governor's description of the police response turned out to be false. days later he would say he'd been misled by his briefers. here is what we know. at 11:28 a.m. on may 24th, a speeding ford pickup truck crashes into a ditch outside the grounds of robb elementary school. the surveillance camera overlooking the parking lot of the hill crest funeral home across the street shows two witnesses to the crash approach the pickup. the driver fires at them, and they run. they then call 911. the 18-year-old gunman now out of the truck walks towards the school. a teacher inside calls 9/11. >> he's shooting. the kids are running. oh, my god. get in the room! get in the room! get in your room! get in your room! >> responding to one of the 9/11 calls, a school safety officer arrives in his vehicles and drives right past the gunman. police initially report this officer, quote, engaged with the gunman. >> he attempted to enter the school or he was engaged by law enforcement, and, unfortunately, he was able to enter the premises. there were several law enforcement that engaged the suspect but he was able to make entry into the school. >> that never happened. as surveillance images show, the gunman was able to enter the school parking lot, fire his rifle 27 times at the building and then walk inside. the next day at the governor's press conference steven mccraw, the director of dps, portrayed the incident in the best light repeating the false story about engaging the insglent there was a brave school district resource officer that engaged him. at that time gunfire was not exchanged but the subject was able to neighboring into the school >> if you came to a scene and you were behind a position of cover and you had your we op drawn on a subject and then you were giving that person commands and they were responding to your commands, you could refer to that as engaging the subject, but let's be honest. its use in this situation was misleading. they didn't do any of those things with the subject. >> andrew mccabe is the director deputy director of the fbi. >> i will say that as a member of the law enforcement community, it's a very tough position to be in. law enforcement people understand what it's like to have to respond to crisis events, how confusing it is, how oftentimes the early information that you get from the scene is inaccurate. we get it. these are like the worst and hardest decisions you'll ever have to make as a law enforcement officer, so we are a community that's reluctant to like immediately criticize each oh, and i certainly felt that way in uvalde. nevertheless, there are all kind of things here that really didn't add up. >> it would take a full day before another dps official, south texas regional director escalon corrected the record. >> one thing that i wanted to mention that i want to clear up that came out early on. it was reported that a school district police officer confronted the suspect that was making entry. not accurate. he walked in unobstructed initially. he was not confronted by anybody to clear the record on that. >> that is even more clear in the surveillance video inside the school. at 11:33 a.m. the gunman opens the unlocked door and walks inside. he heads down a hallway to classrooms 111 and 112 which are adjoined. a child rounds the corner and peers down the hallway. at the sound of gunfire he runs. law enforcement officials say at least 100 rounds are fired by the gunman inside classroom within the first four minutes. while the gunman is shooting in the classroom, a security camera shows three uvalde police officers approach. all three have body armor. two hold rifles, the other a pistol. at 11:36 they rush down the hall towards the classroom. according to the dps timeline, the gunman fired driving them away. the texas house investigative committee report says one officer faced gunfire getting grazed by fragments and building material. according to that report the other officer was also struck with building material. on the other end of the hall a body camera shows uvalde school district police chief pete arredondo, the highest ranking officer on the scene, also near the classroom with sgloefrs careful. shots fired. >> more and more officers arrive but no one makes a move to neutralize the shooter, though clearly some overs know time is of the essence. >> we've got to get in there. we've got to get in there. he keeps shooting. we've got to get in there. >> it's clear police know where the gunman is. >> okay, guys. he's armed. he just went into the building on the west side of the property. >> the day after the shooting at governor abbott's press conference this is what kps director claimed happened. >> the shooting began, we had uvalde police officers arrive on scene along with the independent school officers immediately briefed because we know every second of life. law enforcement officers were there. didn't engage him immediately. did contain him in the class root those officers who arrived on the scene and put their lives in danger they saved other kids. they kept him pinned down and we're very proud that have. >> as the body and the security cameras clearly showers, no one immediately breached the classroom. no one immediately engaged the shooter. no one pinned him down. >> do we know where the try is. >> he was free to roam the classroom killing at will. the word mcgraw uses are vague and misleading. >> he breached it and engaged the active shooter and continued to keep them pinned down in that location, you know, afterwards until a tactical team could be put together. they breached the classroom door. they went in and engaged, killed him at the scene. >> the what we didn't know when mcgraw was saying that is that the shooter was in the school for 77 minutes before the classroom was finally breached and he was killed. during that time, there were dozens of police coming and going, hundreds outside the school and not one of them did what officers around the country are now routinely trained to do in these situations. >> the delayed and extended time that the responding officers really wasted in uvalde is the exact opposite of how law enforcement is supposed to respond to an active shooter. we've learned that most fatalities take place in about the first two minutes an active shooter is on the scene. your number one goal is to get in there and stop that shooter. you have to kill that person before they are able to kill other innocent victims, and that did not happen in uvalde as we now know from the committee's report. there was one effort initially to get into the classroom. they were pushed back by some -- by some return fire from the subject. >> you know that they are kids, right? >> so many parents are still waiting for answers, heartbroken over the unimaginable loss of their children. i met angel garza the day after his shootings. his stepdaughter was only 10 years old. >> i'm a med aid so when i arrived on the scene. they had still kids inside. they started bringing the kids out, and i was aiding assistance. one little girl was just covered in blood head to toe, like i thought she was injured. i asked her what was wrong, and she says she's okay. she was hysterical saying that they shot her best friend, killed her best friend and she's not breathing and she was trying to call the cops and i asked the little girl the name and she told meal an me marie. >> that's how you learned. >> she was so sweet. she was the sweetest little girl who did nothing wrong. she listened to her mom and dad. she always brushed her teeth. she was creative. she made things for us. she never got in trouble in school. i just want to know what she did to be a victim. >> angel told me ane marie jo had just been given her first phone and was trying to call police when she was murdered. coming up, more of what authorities reveal

the gun foyer for the singular purpose of saving livings. >> two days after governor greg abbott and other state officials presented misleading or false information about the attack he was asked about his comments by the reporter. >> [ inaudible ]. >> i was mid led. i am livid about what happened. i was on this very stage two days ago, and i was telling the public information that had been told to me in a room a few yards behind where we're looking at right now. i wrote down hand notes in detail about what everybody in that room told me in sequential order about what happened, and when i came out here on this stage and told the public what happened, it was a recitation of what people in that room told me. >> former fbi deputy director andrew mccabe has led multiple law enforcement responses in crises. >> it's not uncommon to be briefed on inaccurate information, especially early on or while the cries sis ongoing, and so i have a certain amount of, you know, consideration for what happened there. however, we also know that there was video surveillance inside the school that would have shown anybody who cared to look at it the exact amount of time that law enforcement spent basically standing in those hallways doing nothing while people were being killed in those two classrooms, so it is almost impossible to me to believe that the governor and his staffers and the folks that we saw in that press conference on the day of or the day after the shooting didn't have better information, didn't understand the true depth and the significance of that delayed response, and if they didn't know, then shame on them, because the information was right there. they should have known. somebody should have looked at that video and given the governor a pretty robust picture of how bad things actually were, so, yeah, it's almost impossible for me to imagine that they truly thought the world was as they portrayed it in that press conference. >> get in the room! >> another misleading statement repeatedly made by texas officials was that the shooter was somehow barricaded inside the classroom. >> i believe he's barricaded. >> we were at a disadvantage because the gunman was able to make entry into a classroom, barricade himself inside that classroom and that's when he started shooting children and the teachers. >> but he wasn't barricaded. in fact, the door to the classroom may not even have been locked. that's according to a report to the texas statehouse committee no one tried opening the floor. >> this press conference is to give you a snapshot of where we're at today. >> you guys have said that he was barricaded. can you explain to us how he was barricaded and why you guys could not breach that door. >> i have taken all your questions into consideration. we will be doing updates. >> no, you should be able to answer that question now, sir. >> what is your now? >> shimon prokupecz. >> shimon, i hear you. >> we've been given a lot of bad information. why don't you clear all of this up now and explain how it is that your officers were in there for an hour, yes, rescuing people but yet no one was able to get inside that room in. >> shimon, we will circle back with you. we want to answer all your questions. >> i really got the sense that they were hiding something and he told us yeah, officers were there and then the border patrol goes in and kills the gunman. he doesn't tell us what's going on and why. that is really started to get me very angry and upset. >> thank you so much. >> well, victor es:the south texas director of dps isn't answer cnn's shimon prokupecz's questions, he does oufrp another explanation for why no one attended to breach the classroom and kill the gunman. >> we have officers calling for additional resources. everybody that's in the area, tactical teams, we need equipment. >> shield to shield. aren't these ballistic though. >> we need specialty women. we need body armor. we need precision riflemen, negotiators, so during this time that they are making those calls to bring in help to solve this problem and stop it immediately they are also evacuating personnel, i wouldn't say personnel, students, teachers. there's a lot going on. a lot of conflict situation. >> we're going to negotiate and we're waiting for more shields. >> according to andrew mccabe they shouldn't be waiting on any of that. >> be careful. >> the texas state training on active shooter event for school-based law enforcement officers says very clearly that when you arrive at such a scene and such a crisis your job is to go in quickly with whatever equipment and personnel you have in that moment. it is admittedly an incredibly risky dangerous position for law enforcement to be in, and that is part of the job. you are expected to put yourself into that risk, into that danger to take a chance at saving the lives of oh, and that didn't happen here. you know, it's always great to the wait, you know, to have more equipment and bigger guns and more people but, you know, you lose time waiting for those resources, precious time in which your innocent victims may be losing their lives, and that is exactly what happened here. >> spokesman for the texas department of public safety -- >> hours after victor es:'s news conference another dps official seems to give yet another explanation as toss why police did not follow active shooter protocols. >> don't best practices, lieutenant, call for overs to disable a shooter as quickly as possible regardless of how many officers are actually on site? >> correct. the active shooter situation. you want to stop the killing and want to preserve life and also one thing that, of course, the american people need to understand is that officers are making entry into this building. they do not know where the gunman is. they are hearing gunshots. they are receiving gunshots. at that point if they proceeded any further not knowing where the suspect was at, they could have been killed and at that point that gunman would have had an opportunity to kill other people inside that school. >> and i thought that that was the most ridiculous at the same time and, again, making excuses if as he claims or as he claimed that the gunman was in his classroom, what do you mean you don't know where the gunshots were coming from. of course officers knew where the gunshots were coming from. there was a lot of confusion over whether there,was a classroom or an office, yeah, it's very apparent now, but they knew what area of the building the gunshots were coming, from and that lieutenant was also trying to argue that these officers were, you know, taking gunfire and they had to protect themselves and they didn't exactly know what they were dealing with and they needed more firepower and they needed more help and that's why it took so long and, again, trying to give us this kind of glowing picture of the initial response that police did everything right here, that they were the heroes. >> many parents who stood outside robb elementary urging law enforcement to do more. >> if they have got a shot, shoot them or something. >> don't se
