A woman in a car was ramming a man on a motorcycle, chasing him down the streets of Chula Vista, California. A police drone flew after them, broadcasting a live video feed to officers' smartphones.All officers in the department had been out on other high-priority calls when they received the report of two people fighting -- so they deployed their newest emergency response tool. Thanks to the footage from the drone, when officers arrived on scene, they knew exactly where to find the woman and man, and what had happened moments beforehand.They arrested the woman for assault with a deadly weapon, but also found the man happened to be riding a stolen motorcycle. The theft was unrelated to the incident.This is how the Chula Vista Police Department has started using drones to respond to calls, as part of a Federal Aviation Administration program. While police departments have already used drones as part of investigations after a crime has occurred, this program sends a drone out ahead of officers while the crime may still be in progress; officers use that footage to decide how to approach the situation."It gives someone like myself, the Watch Commander, a front row seat to what's going on," said Lt. Christopher Kelly.In the six months the program has been active, drones have helped Chula Vista police make more than 56 arrests. For comparison, Chula Vista police made 6,027 arrests over the course of last year.Police say arrests are up since the drone program began in October compared to the same time period last year, but that it's too early to attribute the change to the drone program.Chula Vista Police Chief Roxana Kennedy said the drones had mostly been operating within a limited range of a mile radius around the station, while the whole city is 52 square miles. "That being said, the drone has effectively contributed to several arrests where it arrived on scene first and vectored officers to the suspect," she said.How the system worksDirected by an officer sitting in the basement of Chula Vista police headquarters, a drone launches from the rooftop.On the roof, another officer sets the geo-fence, a virtual geographic boundary set by GPS, to tell the drone where to go.The pilot on the roof can override the officer directing the drone from the basement if he sees an obstruction, like a flock of birds or manned aircraft, in the way.Federal law typically allows drones to only be flown within the operator's line of sight. The FAA's Integration Pilot Program is letting cities across the United States test flying drones longer and farther, for package delivery, agriculture operations, medical equipment delivery and public safety, among other uses. Along with the city of San Diego, the city of Chula Vista is focusing on the area of public safety operations.Using an off-the-shelf drone and software from a company called Cape, officers can direct the drone via computer from anywhere.Kennedy, the police chief, said the drone is not a replacement for police officers, but it is a tool to help improve the safety of both officers and citizens they're sworn to protect. "It's a game-changer for law enforcement," she said.While a 911 caller may be distraught and may give incomplete or inaccurate information, a drone can get there faster than a police car and zoom in for a closer look.Kennedy said that the zoom feature on the drone's camera allows officers to see a license plate from two miles away, and that kind of tool helps them make better informed decisions and plot a smarter strategy.She said she hopes it could help avoid deadly force incidents — giving officers a chance to assess a situation and to think about how to defuse it before rushing onto the scene."I think that this is so vital for us in law enforcement right now as we're under tremendous scrutiny," she said. The drones could give the officers "real-time information to determine whether somebody actually does have a weapon in their hand, is it not a weapon, is it a pencil, is it something different?"Privacy concerns"Just this morning we saw one come. Someone called about somebody in their yard, and the first thing we saw was the drone," said David Ward, who lives in the city.Some Chula Vista residents have questions about the drones overhead."It might help solve crimes. But I think drones are a little bit of a violation of privacy. Can they look in your window?" said Marie Paniagua.The police chief said the department has done a lot of work to get the community's buy-in."We have worked really hard to make sure that we have policies in place that we address those issues," Kennedy said. "We don't do random patrol with our drones. They're not utilized that way at all. They are not for surveillance. The only time a drone would be used for instance, a search warrant if it was approved through the judge and there was an actual search warrant."Ward said he wants to know whether citizens have a right to see the footage collected, "but I believe that they're doing it to protect people's safety," he said.Future of drone regulationKennedy said Chula Vista has the lowest staffed police department in San Diego County, with 242 sworn officers covering the 52-square-mile area.The eventual goal, she said, is to be able to at least get one drone over a scene within two minutes of a radio call, and to have the drones placed at police stations and fire stations around the city.Capt. Vern Sallee describes the project in three phases: crawl, walk, run."We're getting feedback from them (the FAA) as to what they need to have confidence in our systems, in our drones, to start changing the rules to better integrate drones into the national air space they control," Sallee said.And last month, Chula Vista police drones got clearance to fly farther.On March 15, the FAA granted Chula Vista PD the first-ever certificate of authorization with a "beyond visual line of sight" provision for an Integration Pilot Program participant that allows for proactive emergency response.That gives them a 40-mile flying radius, according to Cape -- and police say those longer drone flights have already started. 6135

A University of North Carolina study warns against the use of THC or CBD by women who are in the early stages of pregnancy. The study, which was published this week, tested the use of both synthetic and natural cannabinoids on mice. The results found that one-time exposure to cannabinoids early in a pregnancy can cause growth issues in a developing embryo. UNC said that this was the first time a study of this kind has been performed on mammals. Researchers said that they found the effects of CBD and THC are potentially very similar to what is seen in fetal alcohol syndrome. The researchers added that cannabinoid use disrupted signaling between molecules and cells that control growth and development. Researchers believe the results on mouse fetuses would be similar to human fetuses.“The development of the embryo in this time period is very similar across all vertebrates,” said Scott Parnell, a member of the UNC Bowles Center for Alcohol Studies. “In this study we also test a synthetic cannabinoid in zebrafish that yielded similar growth deformations as the natural CBs. Having the same results across animal models reinforces our findings.”The researchers administered enough CBD that is considered a therapeutic range for humans. The THC concentration was of similar levels to smoking marijuana. “It is concerning how little we know about the use of marijuana, its CBs, and products like CBD oil during pregnancy,” Parnell said. “We know that there is no safe period to drink alcohol during a pregnancy, and I think this research shows the same is likely true of marijuana use.”To read more on the study, click 1639

Airlines are holding off on orders for Boeing's 737 Max — the latest sign of how deeply the company's best-selling jet has been thrown into crisis.Boeing released data Tuesday that showed only 10 of the planes were ordered in the first two months of 2019. There were no orders in March, the month that a 737 Max jet flown by Ethiopian Airlines pilots crashed in that country, killing everyone aboard. It was the second fatal crash involving a Max in recent months.That small number compares to 112 orders for the plane in the first quarter of 2018. At that time, Southwest Airlines had ordered 40 of the jets, while Ryanair ordered 25.Orders for Boeing's other commercial jets actually increased slightly. The company sold 85 other commercial jets last quarter, compared to 68 a year earlier. But the sales data for the Max gives the clearest picture yet of how much scrutiny of that model could be hurting Boeing's bottom line.Investigators are still probing the cause of the Ethiopian crash, as well as the other Max crash involving a Lion Air jet last October. The two accidents killed 346 people in all, and eventually prompted the grounding of all 737 Max planes last month. Boeing also halted deliveries and announced last week that it was scaling back production of the 737 Max.The focus of the crash investigations is the plane's automatic safety system, for which Boeing says it is developing a software fix. The fatal crashes are not the only cause of the sales drop, said Richard Aboulafia, aerospace analyst for the Teal Group. He attributed much of the change to the massive number of orders for the next generation of single-aisle jets that both Boeing and rival Airbus had previously booked.Airbus actually had worse first quarter orders for its A320, its 737 Max competitor."This is the mother of all frontloaded markets," said Aboulafia.Boeing has orders for 5,000 of the 737 Max jets on its books already. So far only one airline, Indonesia's Garuda, has outright canceled an order for 50 of the 737 Max jets since the grounding.Boeing also said Tuesday that all 737 deliveries in the first quarter fell by a third, to 89 from 132 a year ago. But most of that drop was caused by the reduced production and delivery of the older version of the 737 jet that Boeing is still building for some customers. Deliveries of the the older 737 jets fell by 66% to 32. Deliveries of the 737 Max increased by 54% compared to a year ago to 57, even with a two-week halt. That's because Boeing spent most of 2017 ramping up production of the Max. 2592
