The US Federal Aviation Administration (FAA) proposed a rule change last month to open the skies to more drone flights beyond the sight of operators, seeking to replace the current cumbersome system of case-by-case authorization for such long-range use.
This theoretically would allow more retailers and restaurants to deliver goods and food by drone. The problem with that is economics. Delivery drones cannot carry much weight and have big obstacles for getting the product on the ground with damaging the drone, the goods or the family pet. Moreover, point-to-point deliveries are expensive. A delivery driver normally can make as many as 200 residential stops a day and drop off multiple packages at one place. Wind, rain and snow can impede drone deliveries. These drawbacks are the reason FedEx Corp and United Parcel Service Inc long ago cooled their enthusiasm on the drone-delivery promise.
On the other hand, apart from many military uses, small commercial drones excel at inspection, surveillance and videography. Companies and governments use drones to inspect bridges or home rooftops, to cover news and sporting events, to stage spectacular light shows and to contribute unbelievable aerial shots for movies and nature documentaries.

The ability to provide live, aerial views at the fraction of the cost of a helicopter also makes drones useful for law enforcement and firefighters. Police departments are employing them to track suspects and give officers more situational awareness at crime scenes. A drone can help firefighters search dangerous areas for trapped people. As the FAA relaxes restrictions, you can expect to see more first-responder drones buzzing around the sky. This raises all kinds of privacy concerns. However, if the police can come up with acceptable rules and transparency to safeguard people’s rights, drones can become a powerful tool.
The Las Vegas Metropolitan Police Department this month received FAA authorization for remote pilots to fly drones beyond visual line of sight except near airports and military facilities. In an even bigger breakthrough for drone proponents, the department got the nod to have one remote pilot operate up to four autonomous drones at the same time, Assistant Deputy Sheriff Dori Koren said last week during a presentation by drone maker Skydio. This latter permission would make it much more cost effective for cities nationwide to operate a drone-response program.
Pushback on the use of police drones has already started, spearheaded by the American Civil Liberties Union (ACLU) and groups such as the Electronic Frontier Foundation. The ACLU joined community organizations to sue the Baltimore Police Department to stop an aerial surveillance program, which used light airplanes at the time. A US appeals court ruling in 2021 struck down the program, which by that time had ceased to operate.
Law enforcement can get ahead of privacy concerns and gain public confidence by offering transparency about when drones are deployed and how the data collected during flights is used and stored. Police drones should not be used to patrol the streets and certainly should not be peeking into people’s backyards or windows. Drones should be launched in conjunction only with a 911 call.
This is the policy for the 75-drone fleet of the Las Vegas police, an early adopter of drone technology. Every drone flight is logged and audited to make sure it is in response to an active police call, Koren said at a news conference earlier this month.
The cameras would point up when the drone is on the way to the scene, and the department would not retain any data it does not need, he said.
The drones made by Skydio have flashing red and blue lights and contain a parachute that deploys in case of a midair emergency, he said.
Las Vegas began its “Blue Sky” drone program last year with designated officers carrying drones in the back of police cruisers and launching them when arriving at the scene. With the additional FAA permissions, the program is now switching gears to become much more autonomous.
The department is installing 13 all-weather skyports around the city, mostly at existing police and fire department facilities. These skyports, which double as charging stations, house three drones — one that is deployed and two that serve as backup if the first one runs low on battery power. The drones can launch and land autonomously from the skyports, whose placement around the city can cut response time to seconds.
While the drones are in the air, a remote operator monitoring the video feed can click on a suspect’s car, and the drone automatically follows the vehicle. In one dramatic scene in San Francisco, a police drone tracked a car thief without his awareness and caught him on video stealing license plates to put on his stolen vehicle. Officers were able to follow the thief, and then lay down spike strips to stop the vehicle and arrest the perpetrator without violence or a high-speed chase.
The Las Vegas drone program, even with the limits of launching from the back of police cruisers, flew 1,100 missions since October last year. The drones located suspects in 169 incidents and provided critical support for 386 arrests, Koren said.
That performance would improve with the autonomous drones spread across the city.
There is more drone technology to come. Skydio has a small indoor drone that adeptly flies around objects in tight spaces and can provide surveillance in a building or house, which could be useful for executing search warrants or during a fire. The company is working on a fixed-wing drone that flies farther and is launched with a robotic arm. Skydio cofounder and chief executive officer Adam Bry said that this tracking drone would help reduce or even eliminate dangerous high-speed chases.
One of the main privacy concerns about law enforcement drones is that they could randomly collect, use and share data from video, audio or even sensors, such as heat sensors, while they are airborne. Commitments to only collect and use data during a specific police or fire emergency call should be backed up by independent data audits and by providing the public continuous full transparency about when, where and why drone flights were made. This can all be done automatically and not burden officers with more paperwork.
“What we see with police surveillance technology in general is that there’s a lot of lip service paid up front to the privacy concerns, but then there is mission creep that happens,” Electronic Frontier Foundation senior investigative researcher Beryl Lipton said. “With drones, we’re very concerned about the mission creep.”
As long as police departments take these privacy concerns seriously and use drones appropriately, the small flying machines would save lives, gain public confidence and pave the way for more long-distance commercial drone flights.

Taiwan is rapidly accelerating toward becoming a “super-aged society” — moving at one of the fastest rates globally — with the proportion of elderly people in the population sharply rising. While the demographic shift of “fewer births than deaths” is no longer an anomaly, the nation’s legal framework and social customs appear stuck in the last century. Without adjustments, incidents like last month’s viral kicking incident on the Taipei MRT involving a 73-year-old woman would continue to proliferate, sowing seeds of generational distrust and conflict. The Senior Citizens Welfare Act (老人福利法), originally enacted in 1980 and revised multiple times, positions older
Taiwan’s business-friendly environment and science parks designed to foster technology industries are the key elements of the nation’s winning chip formula, inspiring the US and other countries to try to replicate it. Representatives from US business groups — such as the Greater Phoenix Economic Council, and the Arizona-Taiwan Trade and Investment Office — in July visited the Hsinchu Science Park (新竹科學園區), home to Taiwan Semiconductor Manufacturing Co’s (TSMC) headquarters and its first fab. They showed great interest in creating similar science parks, with aims to build an extensive semiconductor chain suitable for the US, with chip designing, packaging and manufacturing. The
The Chinese Nationalist Party (KMT) has its chairperson election tomorrow. Although the party has long positioned itself as “China friendly,” the election is overshadowed by “an overwhelming wave of Chinese intervention.” The six candidates vying for the chair are former Taipei mayor Hau Lung-bin (郝龍斌), former lawmaker Cheng Li-wen (鄭麗文), Legislator Luo Chih-chiang (羅智強), Sun Yat-sen School president Chang Ya-chung (張亞中), former National Assembly representative Tsai Chih-hong (蔡志弘) and former Changhua County comissioner Zhuo Bo-yuan (卓伯源). While Cheng and Hau are front-runners in different surveys, Hau has complained of an online defamation campaign against him coming from accounts with foreign IP addresses,
When Taiwan High Speed Rail Corp (THSRC) announced the implementation of a new “quiet carriage” policy across all train cars on Sept. 22, I — a classroom teacher who frequently takes the high-speed rail — was filled with anticipation. The days of passengers videoconferencing as if there were no one else on the train, playing videos at full volume or speaking loudly without regard for others finally seemed numbered. However, this battle for silence was lost after less than one month. Faced with emotional guilt from infants and anxious parents, THSRC caved and retreated. However, official high-speed rail data have long
