It looks like former President Moon may continue the tradition of former Korean presidents going to jail:

Former President Moon Jae-in was indicted without detention Thursday on charges of bribery, according to the Jeonju District Prosecutor’s Office.
Moon has been accused of allowing his former son-in-law to receive preferential treatment in securing a job with an airline. Almost 220 million won ($154,000) in salary and relocation expenses to Thailand were paid between July 2018 and April 2020, which constituted a de facto bribe to the former president, according to the prosecution.
Prosecutors launched an investigation into former President Moon Jae-in’s alleged involvement in the case after Seoul-based civic group Justice People filed a complaint in December 2021, alleging a possible quid pro quo involving Moon, his former son-in-law, identified by the surname Seo, and Lee Sang-jik — a former two-term lawmaker from the then-ruling Democratic Party and founder of budget airline Eastar Jet.
Prosecutors pinpointed Lee as the source of the alleged bribe and confirmed that Seo’s appointment as executive director of Thai Eastar Jet was made despite his lack of airline industry experience and the company’s financial struggles. A separate civil affairs team under Moon’s presidential office was involved in the process, the prosecution claims.
“Seo frequently left his post for extended periods, flew to South Korea or worked remotely. He did not provide proper labor befitting his position as the executive director. But Seo received a monthly salary of 8 million won, almost twice the salary of the airline’s CEO,” the Jeonju District Prosecutor’s Office said in a press release.
You can read more at the link, but this was clearly a quid pro quo for his son-in-law to get this job he was not qualified for and apparently put little effort into. With that said imagine if the U.S. had the same corruption laws as Korea? Former president Joe Biden would be getting prosecuted for all the money his son has been making off of his dad’s name and position. Instead you have a whole political party and media establishment covering for him.
