Drones, robots, license plate readers: Police grapple with community concerns as they turn to tech
for their Jobs
Last year, police in Mountain View, Calif., knew they had a potentially dangerous situation on their
hands when a man barricaded himself inside an unlocked three-story townhouse along with the homeowners.
Police received a call from the homeowners, who said the man was armed with a knife. They didn’t
know whether they could safely enter the home and they didn’t know the man’s intentions. So instead of taking
any risk, police called in their trusty sidekick: A camera-equipped drone.
Officers on the ground used the drone to live stream video from the second- and third-floor windows,
giving them the opportunity to assess the gravity of the situation and the location of the suspect. They quickly
learned the man did not have any visible weapons on him.
“There was no risk to life, so we let him sit in there and did our best to communicate with him,” said Lt.
Scott Nelson of the Mountain View Police Department. “No use of force was needed.”
Police across the United States are increasingly relying on emerging technologies to make their jobs
more efficient. They are using drones, license plate readers, body cameras and gunshot detection systems to
reduce injury and bodily harm. The move comes as some law enforcement agencies are struggling with
retention and hiring during the pandemic, when hundreds of cops in cities including Los Angeles and New York
were sidelined because of the spread of the coronavirus. As police departments determine which technologies
to adopt, they are also grappling with growing concerns about privacy that these technologies bring and
potential complications they could create for officers on the job.
“Tech can be a great tool for law enforcement to use,” said Sgt. James Smallwood, Nashville-based
treasurer of the national Fraternal Order of Police. But “as with anything else, we have to balance the line of
privacy and meeting the expectation to promote public safety.”
DJI, the Chinese tech company that makes many of the drones adopted by police departments, said
more than 1,000 police departments across the country use some type of drone. Drones are proving to be a
police force multiplier across the nation, aiding with everything from lost children to dangerous suspects to
crash reconstruction. But Lisberg doesn’t think they’ll ever replace police officers.
“You need a sense of humanity at work in policing,” he said. “A drone is a tool that helps accomplish
the goals [police] already have. [To] do it better, safely and more efficiently.”
Drones aren’t the only tech tools that police say have made them more efficient. More than 120 cities
are using gunshot detection systems, which alert police to gunfire within the devices’ coverage area.
The systems use sensors and algorithms that can identify and determine which loud bangs are
probably gunshots. Within about 60 seconds, they can alert police to the precise location in which the gunshots
were heard. That allows police to better deploy their resources.
“Police chiefs are looking for innovative ways to deal with the responsibilities they have,” he said.
“They’re finding ways to provide them even in areas where budgets are tight.”
To be sure, not all of the technology is proving to be positive, says Griffith of Houston’s police union.
He noted that while tech can add a level of efficiency, it also can increase stress levels for officers, who have
been experiencing increased scrutiny for excessive use of force and discriminatory practices in recent years.
Body cameras, for example, can help police and the community better understand the details around an
incident in which an officer resorted to use of force. But the cameras also can catch small, sometimes minor
policy violations from police that don’t affect the overall outcome of any situation, such as whether a police
officer buckled his seat belt before pressing the gas, Griffith said.
“We know that there will be more tech coming,” he said. “But we pray it’s something that will help
[officers] and not make it to where they have to be perfect every minute of every day.”
Police also have to walk a fine line when it comes to implementing new technology, taking into account
the community’s comfort level and privacy concerns, they say.
Farhang Heydari, executive director of the nonprofit Policing Project at New York University School of
Law, said he’s mostly concerned with increasing access to private cameras and third-party databases and the
ability to tie them together, which could create a new kind of surveillance, he said.
That has the potential to magnify some of the harms of policing, like the overenforcement of low-level
crime or the exacerbation of racial disparities. Ultimately, Heydari says, police shouldn’t be charged with
deciding on their own what technology to use. Regulators and communities should, he said.

California woman arrested in theft of 65 Stanley cups - valued at nearly $2,500
By C Mandler
January 22, 2024 / 3:05 PM EST / CBS News
On Jan. 17, police in Roseville, California, discovered a 23-year-old woman had allegedly absconded with 65 Stanley cups from a nearby store — worth nearly $2,500.
"Staff saw a woman take a shopping cart full of Stanley water bottles without paying for them," said the Roseville Police Department in a statement on Facebook.
After being confronted by retail staff, the woman refused to stop, stuffing the cups into her car. She was subsequently arrested on a charge of grand theft and has yet to be identified by officers.
"While Stanley Quenchers are all the rage, we strongly advise against turning to crime to fulfill your hydration habits," said the Roseville police.
One commenter on the post pointed out that in addition to the trove of cups in the trunk and front seat, there was also a bright red Stanley cup in the cup holder, which they hoped police also confiscated. Colorful Stanley cups caused consumer mayhem earlier this month when the brand dropped a limited-edition batch of Valentine's Day colors of the popular tumbler at in-Target Starbucks locations.
Viral video showed shoppers running toward displays of the cups, as well as long lines of consumers waiting to get their hands on one of the coveted Quenchers.

Car crashes into second floor
of Pennsylvania home
A man drove his car into the second floor of a
Pennsylvania home on Sunday in what officials say was an
"intentional act".
Charges are pending against the driver after police found
a grey vehicle sticking out of the side of the house in the city
of Lewistown.
Officials have not said how exactly the vehicle made its
way to the second floor.
"The pictures speak for themselves", a fire official told the
BBC.
Anywhere from one to three people were inside the home
at the time of the crash but were not injured, according to
Sam Baumgardner, an administrator at the Junction Fire
Company, which assisted in the response to the crash.
The driver was able to climb out onto the roof after the
crash and was taken to the hospital with injuries, Mr
Baumgardner said.
He added that the car likely hit the second floor because
of a culvert - a tunnel that carries a stream under a road or
railway - on the left side of the house.
The driver "went into the culvert and propelled into the air
and landed on the second floor", Mr Baumgardner said.
In a report, Lewistown police said they had determined
through an investigation that the crash was "an intentional
act".
Officials added that the driver will face charges for the
crash.
The BBC has reached out to police for comment.
The fire department said it took about three hours to
remove the car from the second floor.
"The crew that was on the rescue definitely had to think
outside the box," Mr Baumgardner said.
Rescue crews helped stabilise the house and put a tarp
over the hole from the crash because of upcoming storms,
the Junction Fire Company said in a post on Facebook.

Impact of Climate Change on Firefighting
Extends Beyond Wildfires
Global warming is often mentioned as a factor in the
accelerating frequency and intensity of wildfires. However, there
are other consequences of global warming that impact the fire
service, including new hazards and medical emergencies,
emerging training challenges, population migration, and
technology developments.
Climate change is often discussed as a future event. However,
the impact of wildfires is just the most obvious example of how
climate change is already impacting the world, and fire and
emergency personnel will be called on to mitigate the effects.
The most obvious and extreme impact of global warming can
be seen in the increase of frequency and intensity of wildfires.
Hotter and drier weather is extending the wildfire season (maybe
to become year-round?). Higher temperatures, low humidity, less
rainfall, and high wind increase the likelihood of wildfires.

Text 1A2-II
Chagas disease, also known as American trypanosomiasis, is
a potentially life-threatening illness caused by the protozoan
parasite Trypanosoma cruzi. About 6-7 million people worldwide
are estimated to be infected with T. cruzi. The disease is found
mainly in endemic areas of 21 continental Latin American
countries, where it has been mostly transmitted to humans and
other mammals by contact with feces or urine of triatomine bugs
(vector-borne), known as kissing bugs, among many other
popular names, depending on the geographical area.
Chagas disease is named after Carlos Ribeiro Justiniano
Chagas, a Brazilian physician and researcher who discovered the
disease in 1909. Chagas disease was once entirely confined to
continental rural areas of the Region of the Americas (excluding
the Caribbean islands). Due to increased population mobility
over previous decades, most infected people now live in urban
settings and the infection has been increasingly detected in the
United States of America, Canada, and many European and some
African, Eastern Mediterranean and Western Pacific countries.
Chagas disease’s transmission is caused by T. cruzi
parasites, which are mainly transmitted by contact with
feces/urine of infected blood-sucking triatomine bugs. Normally
they hide during the day and become active at night when they
feed on animal blood, including human blood. They usually bite
an exposed area of skin such as the face (hence its common
name, kissing bug), and the bug defecates or urinates close to the
bite. The parasites enter the body when the person instinctively
smears the bug’s feces or urine into the bite, other skin breaks,
the eyes, or the mouth. T. cruzi can also be transmitted by
consumption of food or beverages contaminated with T. cruzi
through, for example, contact with feces or urine of infected
triatomine bugs or common opossums. This kind of transmission
typically causes outbreaks with more severe cases and mortality;
passage from an infected mother to her newborn during
pregnancy or childbirth; blood or blood product transfusion from
infected donors; some organ transplants using organs from
infected donors; and laboratory accidents.
Internet: <who.int> (adapted).
Regarding the transmission of Chagas disease, according to text
1A2-II, judge the following items.
I Blood product transfusion from infected donors can transmit the disease.
II The also called kissing bug’s feces and urine carry the protozoan parasite.
III Infected pregnant women cannot contaminate their babies during pregnancy or childbirth.
IV Contaminated food or drinks can transmit Chagas disease to people.
Choose the correct option.

Text 1A2-I
In 2020, the state of California experienced its worst
wildfire season on record, with the Bay Area fire becoming one
of the largest wildfires in American history. By the end of the
year, the state recorded more than 8,600 blazes that burned down
over 4 million acres of land, accounting for more than 4% of the
state’s total land area.
California is known for its wildfire seasons, which usually
take place between late summer and early autumn, though they
have been getting significantly more intense, destructive, and
longer in the past two decades. At least one-third of the worst
wildfires in USA (United States of America) history occurred in
California. But what causes California such susceptibility to
wildfires in the first place and what is causing the exacerbation
of it?
Wildfires can occur naturally and as a result of human
activity, but three elements must be present for a wildfire to start.
Fuel: Any flammable material surrounding a fire, which can
come in the form of live or dead trees, dry vegetation, and other
organic matter; Air: An abundance of oxygen supply. Heat
sources: to ignite and burn the fuel. This could take the form of
lightning strikes or human sources such as campfires or
cigarettes.
Natural wildfires, which are classified as natural disasters
by the Environmental Protection Agency, can start during low
precipitation, dry weather and droughts. During these conditions,
dry vegetation becomes the perfect fuel for wildfires and when
lightning strikes, it ignites a fire that can spread rapidly with the
aid of strong winds and elevated temperatures.

Why Climate Change Could Mean
More Delayed Flights
No one enjoys a delayed flight, but as our weather gets
warmer, we can expect more of them.
That's according to experts, who say that the heat of the
summer might cause more delays.
Bloomberg looked at US data for flight delays at airports in
Chicago and New York from June to August in 2022 and from
January to March in 2023. It found that there were more
delayed flights in the summer months at both airports.
When the temperature rises above 39 degrees Celsius,
things get very difficult for airlines, Bijan Vasigh, a professor
at Embry-Riddle Aeronautical University in the US,
told Bloomberg.
The air is thinner when it gets hot and that makes it harder
for planes to take off. In thinner air there is not as much lift, so
more power is needed.
When they need more power, it helps to have a lighter
airplane.
That might mean pilots have to make last-minute decisions
to reduce the weight on board by dumping fuel, passengers
or baggage — meaning the plane will probably be delayed.
The problem gets worse at airports that are at a higher
altitude where the air is already thinner, and at airports with
short runways, since planes need more space to get up to a
high speed.
But thin air is not the only problem. Smoke from wildfires —
that have been happening all around the world in the summer
of 2023 —can also cause flights to be delayed and canceled.
Of course, the summer is also a busy time when millions of
people fly, and weather is not the only cause of delays — but
our hotter climate doesn't seem to be helping.
