President Yoon's ”arrest drama” was broadcast live across the nation... How was it possible? = South Korea

With the execution of the arrest warrant for President Yoon Seok-yeol being broadcast live to the entire nation, interest is also growing as to why the arrest process was made public.
The High-Ranking Public Officials Crime Investigation Agency executed an arrest warrant for President Yoon at his official residence in Hannam-dong, Yongsan-gu, Seoul at 10:33 a.m. on the 15th and took him into custody.
Prior to this, broadcasting stations began broadcasting special news reports at around 4:20 am on the 15th, when part of the arrest team from the Public Prosecutor's Office arrived in front of the Prime Minister's Office, and broadcast the arrest process live in real time.
The live broadcast showed police using ladders to move into the residence, the arrest team using ladders to climb over the car wall, and the entire process of the arrest team entering the residence and breaking through the first to third lines of defense.
The entire process was broadcast live from an aerial perspective. The arrest of a sitting president was an unprecedented event, but the way in which it was made public was also unprecedented.
According to Yonhap News, the area around the government complex in Hannam-dong, where the presidential residence is located, is a restricted protected area under the Military Secrets Protection Act, and photography is usually restricted there.
The security service restricted access to the rooftops of nearby buildings, where visitors could see into the official residence grounds, and security corps from the Seoul Metropolitan Police Agency restricted access to the exterior of the official residence.
Some have questioned why live broadcasting was possible despite the arrest and execution.
It was reported that it was quite difficult to find a place to take pictures on the grounds of the official residence. The most popular "shooting spot" was a large hotel in Namsan. Some media outlets reported that
From his hotel room, he used a telephoto lens to capture the arrest team's movements within the grounds of the Prime Minister's residence, 700 to 800 meters away. However, there is a possibility that there may be legal issues in that he filmed in a security area.
During the first arrest attempt, the Presidential Office filed charges against some media outlets that had filmed the interior of the residence and President Yoon taking a walk.
However, many in the legal profession believe that there is a high possibility that the illegality will be ruled out, given the public interest of the news.
It is difficult to believe that military secrets were leaked just because footage of a walk and parts of the presidential residence was taken. In particular, the presidential office, which is the subject of the accusations, will likely lose the motivation to make further accusations due to President Yoon's arrest.
There is also analysis that suggests this.
