What is a stair climber? Is it illegal to climb a building at high altitude?

In recent years, this kind of "stair climber" has appeared in many countries. In order to pursue excitement and challenge tall buildings everywhere, it is understood that the "stair climber" originated from stair climbing photography. In order to meet the needs of high-altitude shooting, photographers climbed to the top of tall buildings to find seats (shooting locations) and record the city scenery. Later, in order to seek excitement, some people gradually deviated from the original intention of climbing stairs, and derived extreme cool running or extreme selfie for climbing stairs. Are there many unexpected failures of stair climbers? In Russia, more than 10 people have died from selfies this year. According to foreign media reports, in Russia, many people often take selfies regardless of danger, such as taking selfies with TV antennas on the roof. According to Russian police statistics, more than 10 people in Russia have paid the price of their lives for dangerous selfies this year. I hope everyone will take a warning and don't joke about their lives! I often see such photos on social networks: several young people standing on the roof of a skyscraper under construction without any safety protection measures, posing or dragging or cool or small and fresh shapes, and onlookers are full of praise and worship. They have a special name, called "Stair Climbers". When climbing stairs meets photographers, especially when selfies become a new trend, the conspicuous nature of social networks greatly encourages the motivation of "climbing stairs". Now "stair climbers" have long been the most common labels and groups, and are no longer an alternative hobby of a small number of people. There are also many stair-climbing enthusiasts who share the secrets of climbing stairs with each other, and some people explain in detail where the plane seats are good and where the security check is strict. From a moral point of view, once any object, including tiles, gravel, glass, etc. All of them were knocked off in the process of climbing stairs, and falling from the air hundreds of meters high would pose a great threat to the property or life of others. Therefore, such willful climbing stairs is first of all a lack of public morality. From a legal point of view, there are more problems. First, disturb public order. Entering a building without the consent of the building owner, manager or user is suspected of disturbing public order. The second is to endanger public safety. Climbing buildings are high in height, and some of them are not yet open, so the probability of danger is high, which is easy to damage the personal and property safety of third people around them and endanger the safety of the public. The third is infringement of legitimate rights and interests. The owner of a building has the right to possess and use the building and the ownership of the public part. The climber entered the building without authorization, which violated the legitimate rights and interests of the building owner.
