Mass shootings and acts of terrorism may dominate headlines, but it's the homicides and, to a lesser extent, the suicides that happen out of the spotlight that make up the bulk of firearm-related deaths around the world, according to a study published Tuesday in the journal JAMA. More gun deaths happened outside of war than in it during the years researchers examined (1990 through 2016) in 195 countries and territories.Worldwide, an estimated 251,000 people died by gun in 2016. In 1990, there were 209,000 firearm-related deaths. Accounting for population growth, that's an annualized rate decrease of 0.9 percent.Gun deaths are predominantly concentrated in six countries that make up less than 10 percent of the world's population. The United States, Brazil, Mexico, Colombia, Venezuela and Guatemala together account for more than half of the gun-related deaths worldwide.In 2016, the majority of global firearm deaths -- an estimated 64 percent -- were homicides. Suicides accounted for 27 percent of the gun deaths. A small fraction, about 9 percent of gun deaths, were accidental.If you were to look on a map, the highest numbers of gun-related homicides are concentrated in a belt that stretches from Mexico through the Caribbean to Brazil. Many of these homicides involve drug cartels, the authors suggest, and there's a problem with organized crime and the illegal gun trade.El Salvador saw the greatest concentration of gun-related homicides in 2016, with 38.9 per 100,000 people. By comparison, Singapore, the country that had the fewest, had 0.1 gun-related homicides per 100,000."The sheer magnitude of these deaths and the range in firearm-related deaths is extraordinary," said the study's senior author, Chris Murray, director of the Institute for Health Metrics and Evaluation at the University of Washington.The most vulnerable demographic to gun violence was men between 20 and 24 years old. Men were also the biggest perpetrators of gun violence.Suicide-by-gun rates declined globally between 1990 and 2016. Some countries, though, struggled with this public health crisis. In 2016, Greenland had the highest number of firearm suicides, with 22 deaths per 100,000 people. The US had the second-highest number, with 6.4 deaths per 100,000 in 2016."The US really has quite marked rates around suicide," Murray said. "That was a surprise to me."For perspective, the United States has 4.3 percent of the world's population, but suicide by gun there represented 35.3 percent of all firearm suicides in the world in 2016. By comparison, there were twice as many firearm suicides as gun-related homicides in 2016 in the US.Americans also own more guns per capita than residents of any other country, with about four in 10 Americans saying they either own a gun or live in a home with guns, according to a 2017 Pew Center study.Americans have been killing themselves more with guns over the past decade, but homicide numbers have been relatively flat. The US ranks 30th in the world for total number of homicides, according to the study.The highest increase in gun-related suicide rates in this time period was in Jamaica, and Singapore had the fewest gun-related suicide deaths. These numbers, Murray said, are an important reminder about how widespread this public health problem is.There is no one single trend behind gun violence. Drugs, alcohol, a lack of mental health services and domestic violence are often to blame, as is poverty, the study suggests."Places with high rates of firearm mortality that are getting worse tend to be places with weak government institutions, especially in the criminal justice system or social upheaval," Daniel Webster, who has written extensively about gun violence as director of the Johns Hopkins Center for Gun Policy and Research, wrote in an email. Other things that stood out from these numbers, he said, is that while the "measures aren't great," he said, "there is a connection: more guns, more gun-related deaths."Webster, who was not involved in the new research, added that the general downward trend in firearm mortality is something that stands out because "we tend to think of our current rates of gun violence as the worst ever, but there has been great progress" toward stemming some of this violence.Laws that seem to limit gun violence include ones that strengthen background checks and require permits for ownership, the study authors said. More restrictions on guns in Brazil and South Africa seem to suggest a link between a reduced access to gun ownership and a lower number of gun-related suicides and homicides. 4601

LOUISVILLE, Ky. (LEX 18) — Chief of Police Robert J. Schroeder is declaring a state of emergency for the Louisville Metro Police Department (LMPD) as they wait for Attorney General Daniel Cameron's decision whether or not to indict the officers in the Breonna Taylor case.The department has canceled all off days and vacation requests until further notice."The public may also see barriers being staged around downtown, which is another part of our preparations," Sgt. Lamont Washington said in the statement. "It is important to note that the AG has no timetable for the announcement."Taylor, a 26-year-old emergency medical worker, was killed by Louisville police serving a "no-knock" narcotics search warrant at her apartment. They found no drugs in her home. The city announced a settlement with the Taylor family last week that included a million payment and changes to department policies.An officer was shot during the raid by Taylor's boyfriend, who has said he thought he was defending against a home invasion. The boyfriend was initially charged, but those charges were later dropped.The Louisville Metro Police Department fired one of the officers involved, Brett Hankison, in June, saying he violated procedures by showing "extreme indifference to the value of human life." The other officers involved in the case — Jon Mattingly and Myles Cosgrove — have been placed on administrative reassignment."To ensure we have the appropriate level of staffing to provide for public safety services and our policing functions, effective immediately the LMPD will operate under the emergency staffing and reporting guidelines as outlined in the Standard Operating Procedures, Emergency Response Plan, and collective bargaining agreements until further notice," a memo sent Monday to all personnel states.A handful of buildings around Louisville have been identified as potential places for "backlash" if a decision is announced this week. Windows have been boarded up at the Gene Snyder U.S. Courthouse & Customhouse. The courthouse is closed this week according to an official order, with planned court business rescheduled or moved online.This story originally reported by Jordan Mickle on LEX18.com. 2221

MANAGUA, Nicaragua (AP) — Hurricane Eta is quickly gaining force as it heads for Central America, threatening massive flooding and landslides across a vulnerable region. The National Hurricane Center says the storm has 150 mph sustained winds, as of Monday evening, and is gaining speed as it approaches land. The hurricane was just 6 mph shy of category 5 strength. Eta is expected to hit along the Nicaragua-Honduras border, with landfall coming sometime on Tuesday. The rainfall is expected to be heavy, it could be three feet in some places. The storm surge is predicted to get as high as 12-18 feet above normal tide. "Through Friday evening, heavy rainfall from Eta will likely lead to catastrophic, life-threatening flash flooding and river flooding across portions of Central America, along with landslides in areas of higher terrain. Flash and river flooding is also possible across Jamaica, southeast Mexico, El Salvador, southern Haiti and the Cayman Islands," according to the advisory from the NHC. 1021
