Drone technology offers us world-changing possibilities—from a historic shift in e-commerce to faster emergency response. But technology also has its dark side. It can be used to monitor, threaten critical infrastructure, or attack crowds and public places. "U.S. Homeland Security Secretary Kirstjen Nielsen wrote in The Washington Post.
Venezuelan President Maduro encountered a "drone attack" while attending an open-air event on the 4th. The suspect allegedly manipulated two drones loaded with explosives to attempt an assassination. While the outside world is paying attention to the mastermind behind the scenes, the pros and cons of drones have once again become the focus of public opinion. In order to suppress the threat of drones, drone jammer appear in front of people.
Reports have pointed out that if the "assassination" claim is true, it will be the first drone attack against a head of state, and it may also be a dire harbinger of the future. There are also security experts who worry that the threat of drones may appear frequently in the future, and armed groups may even use drones to launch biological and chemical attacks. Drones are developing rapidly and each has its pros and cons.
In recent years, the civilian drone market has boomed due to factors such as technological advancements, increased supply, and falling prices. This emerging electronic product that combines practicality and leisure is gradually integrated into people's daily work and lives. Small in size, light in weight, and easy to carry, drones can not only complete tasks that are difficult for humans to complete, but also have entertainment functions such as recording life scenes.
A "quadcopter" is a more common type of drone, sometimes referred to as a "quadrotor". This type of drone can be operated remotely and can fly for more than 20 minutes on a single charge. It is cheap and easy to buy. However, the "elf" has a limited load and can easily transform into a deadly weapon, even threatening social security.
Extremist groups have seized on technological advances as an opportunity to innovate tactics. Extremist groups such as the Islamic State have reportedly used drones to carry out attacks, including throwing grenades and ramming infrastructure. With the help of new technologies, extremist groups can use low-cost tools to inflict lethal damage on powerful enemies. Worryingly, the drone threat is not limited to the Middle East theater.
In January 2015, an out-of-control drone crashed on the White House lawn, raising concerns about the safety of the US president. Shortly thereafter, a drone carrying radioactive materials flew into the residence of the Japanese prime minister. It was found that it was a man protesting Japan's nuclear policy. In April, Saudi security forces shot down a drone near the royal palace, amid reports pointing to a "coup attack".
It has been argued that drone strikes by non-state actors have a limited impact. Scott Stewart, an analyst at the Stratfor security consultancy, noted that military drones are extremely difficult to come by, while homemade bombs are usually much less lethal.
Some experts still worry that the psychological impact of a successful small-scale attack may far exceed the actual damage, thereby achieving the attacker's goal of spreading terrorism. Extremist groups such as the Islamic State and Al Qaeda have achieved this goal. Colin Clark, an analyst at the RAND Corporation, a policy think tank, pointed out that this is an important aspect of terrorism-the psychological aspect, even if it does not cause a large number of casualties, an attack can still induce fear. In the face of so many threats from drones, drone signal jammers are particularly important.
