The British BBC analyzed the frequent "indiscriminate crimes" that have recently occurred in South Korea, including at Shinrim Station in Seoul and Seohyun Station in Seongnam. The BBC used the expression "Mudjima", which is an English translation of the Korean word "don't ask" to describe the growing anxiety in South Korean society, The BBC assessed that this was a time when appropriate measures were needed.

On August 13th (local time), the BBC reported in an article titled "Don't ask why - South Korea struggles with a series of indiscriminate incidents," that South Korea is suffering from a series of copycat crime teasers as well as knife abuse incidents.

On July 21st, Cho Sung (33), killed a man in the Sinrim Station area. Three days later, Choi Won-jung (22) drove his car onto the sidewalk near Seohyun Station and then attacked people indiscriminately with a knife. One person died and 13 were injured.

South Korea's violent crime rate hit its lowest level in a decade last year, the BBC said, adding that recent indiscriminate crimes have raised awareness that society is in danger. In fact, the BBC reported that comments on YouTube and other media made comments such as, "South Korea is no longer one of the safest countries in the world."

In South Korea, the public called such crimes "Mudjima crimes," and the South Korean police defined them as "crimes with unusual motives" last year. A total of 18 "indiscriminate incidents" were counted by the police in the first half of this year.

However, the BBC analyzed that South Korea's overall crime rate does not fall under the category of a "dangerous country" yet. South Korea has a homicide rate of 1.3 per 100,000 population, half the Organization for Economic Cooperation and Development (OECD) average and less than one-fifth of the US. One of the reasons is that there is strict firearms control here unlike the United States.

The BBC also recommended that South Korean society should take appropriate treatment and respond to the psychological pressures of unstable living and work. "We need social systems and policies, such as emotional support, that can help people who are fundamentally cut off from society," Song Hyo-jeong, professor of sociology at Korea University, said in an interview with the BBC.
