 The New York City Police Department released surveillance video Thursday of a man, later fatally shot by police, pointing a silver object at residents as if he were brandishing a gun.The video also shows 911 call transcripts of neighborhood residents who reported the man to police.On Wednesday, police shot and killed the black man, identified as Saheed Vassell, in Brooklyn after he pointed what officers believed was a gun at them, authorities said.After the shooting, officers discovered that the object was "a pipe with some sort of knob on it," Chief of Department Terence A. Monahan said at a news conference.Vassell's death comes amid a resurgence of questions about law enforcement's unequal treatment of people of color following another police shooting recently in Sacramento, California. Police there said they thought Stephon Clark had a gun, but only a cell phone was found near his body.New York's attorney general opened an investigation Thursday morning into Vassell's death, said Amy Spitalnick, a spokeswoman for Attorney General Eric Schneiderman."We're committed to conducting an independent, comprehensive and fair investigation," she told CNN.New York City Mayor Bill de Blasio said Thursday the city will be "as transparent as we can in this situation."He also hypothesized what might have happened if the man actually did have a gun."Let's play out the scenario had it been different," he said. "If this individual with a loaded weapon, who for whatever reason, including a mental health challenge, was ready to use it, that's a split-second matter of trying to save lives right then and there."How you get the full facts of what the person has in their hand, and what their mental health condition might be, and are they known to anyone, in something that's playing out in seconds and minutes, that's a very tall order," de Blasio said.'Two-handed shooting stance'The incident started shortly before 5 p.m. Wednesday when officers received 911 calls of a man aiming what callers described as a silver firearm at people in Brooklyn, Monahan said."Three different 911 callers described a man with a gun, pointing it at people on the streets," he said.When officers arrived at the scene, they found a man matching the description provided by the callers, Monahan said."The suspect then took a two-handed shooting stance and pointed an object at the approaching officers, two of whom were in uniform," he said.Four officers discharged their weapons, striking the man, Monahan said. Then they gave him first aid and called for an ambulance to take him to the hospital, where he was pronounced dead."It appears we fired 10 rounds between the four officers," Monahan said. The unidentified officers, who were not wearing body cameras, discovered the metal pipe at the scene.911 transcripts releasedIn transcripts released Thursday by New York police, 911 callers appeared somewhat uncertain about what object Vassell was holding."There is a guy in a brown jacket walking around pointing -- I don't know, (to someone else) what is he pointing in people's face? They say it's a gun, it's silver," one caller said, according to a police transcript."There's a guy walking around the street, he looks like he's crazy, but he's pointing something at people that looks like a gun and he's like popping it, as if, like if he's pulling the trigger," another caller said.A third caller said the man is holding a gun.De Blasio emphasized that 911 dispatchers and police were responding to those fear-filled reports."If that's what officers were responding to in real time, we've got to recognize that if they believe they are dealing with an immediate matter of life and death to the people in the surrounding area, that's an exceedingly difficult, tense, split-second decision that has to be made," he said.By state law, the attorney general is appointed as a special prosecutor to oversee investigations into and prosecute matters related to incidents in which unarmed civilians die during interactions with police or incidents in which there is significant question as to whether the civilian was armed and dangerous, Spitalnick said, citing the law.'He's polite ... kind'Brooklyn resident Eric Vassell told CNN affiliate NY1 that the victim was his 35-year-old son, Saheed.Saheed Vassell had no access to guns and suffered from bipolar disorder, his father told the station."He's polite, nice, he's kind. He just comes and he goes," his father said.Mayor Bill de Blasio said his understanding was that Vassell had mental health issues."What I understand is the family members have already said publicly this is someone who had a profound mental health problem, was not on medication, hadn't been on medication," he said.Renewed calls for police reformPublic fury over the shooting deaths of people of color by law enforcement, which gained traction through the Black Lives Matter movement, swelled again last month after police in Sacramento killed Stephon Clark, an unarmed, African-American father.In light of Clark's killing, which sparked weeks of protests, California lawmakers have proposed a drastic change that would limit the scenarios in which police officers can use deadly force. The bill would replace the "reasonable force" rule with a stricter "necessary force" standard.The proposal also would establish that a homicide by an officer is "not justified if the officer's gross negligence contributed to making the force 'necessary,'" according to the proposal. 5550

(CNN) — California high school and middle school students will have some lifesaving information at their fingertips as they go back to school this year.A law that went into effect in July requires schools to print the number for the National Suicide Prevention Lifeline on student ID cards for seventh- through 12th-graders in public, private and charter schools.That number is 1-800-273-TALK (8255).The law also says that student IDs may have information on the Crisis Text Line — which can be reached by texting HOME to 741741 — as well as local suicide prevention resources."I think any opportunity for somebody to have a number to be able to call out to, reach out to and be available, I think it's fantastic," Ray Morgan told CNN affiliate KGO. His daughter is a freshman at a San Francisco Bay Area high school.The move comes as suicide rates continue to rise in the United States.The suicide rate in 2017 was 33% higher than it was in 1999, according to annual research published in June by the US Centers for Disease Control and Prevention's National Center for Health Statistics.A study published in the medical journal JAMA found a significant increase in the suicide rates among 15- to 24-year-olds between 2000 and 2017.Dave Muth, who advocated for the law, told CNN affiliate KESQ that he hopes it encourages people to talk openly about suicide and mental health. His daughter Madeline died by suicide in 2015."This is a way of remembering her, honoring her and helping to break down the stigma and change policy so that other families don't have to experience what we did," Muth said last year when then-Gov. Jerry Brown signed the measure.To get help, call the National Suicide Prevention Lifeline at 1-800-273-TALK (8255). There is also a crisis text line. For crisis support in Spanish, call 1-888-628-9454. 1832

 Demi Lovato is experiencing "complications" and remains hospitalized following her apparent drug overdose, two sources close to the singer tell CNN.Those complications include "nausea, vomiting and a high fever," the sources say.Although she's expected to "make a full recovery," there is "no estimate" as to when she will be released from Cedars-Sinai Medical Center?in Los Angeles."[We are] taking it day by day," one of the sources said.No information has been released regarding what led to her hospitalization.There were reports Lovato overdosed on heroin, but a source close to the singer denied that.Last week, a source with knowledge of the matter told CNN that Lovato plans to seek drug abuse treatment following her release from hospital care.CNN previously reported that Lovato's family and her former boyfriend, Wilmer Valderrama, have been by her side since her hospitalization one week ago.At the time of her apparent overdose, a representative released a statement saying Lovato was "awake and with her family.""Demi is awake and with her family, who want to express thanks to everyone for the love, prayers and support," said the statement from Lovato's representative. "Some of the information being reported is incorrect and they respectfully ask for privacy and not speculation as her health and recovery is the most important thing right now."Lovato has been open about her struggles with an addiction to cocaine and alcohol, as well as mental health issues and an eating disorder. She also sought professional help for substance abuse and entered rehab in 2010."You just have to take it one day at a time; some days are easier than others and some days you forget about drinking and using, but for me, I work on my physical health, which is important, but my mental health as well," Lovato said, adding that she was seeing her therapist twice a week. "I make sure I stay on my medications. I go to AA meetings. I do what I can physically in the gym. I make it a priority."In the hours after news of her hospitalization broke, fans of the singer took to social media with the hashtag, #HowDemiHasHelpedMe to talk about how she and her music have helped them with their own struggles.Lovato released a single in June called, "Sober" in which she revealed she had relapsed after six years of sobriety."I'm sorry for the fans I lost who watched me fall again," Lovato sings on the track. "I want to be a role model but I'm only human. I'm sorry that I'm here again. I promise I'll get help."Lovato has been touring and promoting her music in recent months.She last performed July 22 at the California Mid-State Fair in Paso Robles, California.CNN has reached out to Lovato's representative for comment 2747

(CNN) -- Cruise passengers held their breath as a 22.5 meter wide cruise liner became the largest boat to pass through Greece's narrow Corinth Canal, according to its operator.Carrying 929 passengers on board, the Braemar cruise liner narrowly managed to squeeze through the rocky walls of the canal -- which measures a maximum of 25 meters wide at the water's surface -- making it the longest boat to make the journey, cruise company Fred Olsen said.The Corinth Canal is a tidal waterway connecting the Gulf of Corinth with the Saronic Gulf, dividing the Pelopónnisos from mainland Greece.Ships have been navigating through the narrow waterways since 1893, but on Wednesday, Fred Olsen claimed to have captained the longest cruise ship through the canal. The ship weighs 24,344 gross tons, and is 195.82 meters long."Today Braemar made history as the longest-ever ship to cruise through the CorinthCanal," Fred Olsen cruise liners said on social media.At 6.3km (3.9 miles) long, the Corinth Canal shortens the sea route from Italian ports to the port of Athens."This is such an exciting sailing and tremendous milestone in Fred Olsen's 171-year history, and we are thrilled to have been able to share it with our guests," Clare Ward, director of product and customer service for Fred. Olsen Cruise Lines said in a statement."At Fred Olsen, we strive to create memories that last a lifetime, and with guests on board Braemar able to get so close to the edges of the Corinth Canal that they could almost touch the sides, we know that this will be a holiday that they will never forget," she added.Talk about a tight squeeze. 1631
