After experiencing a life-threatening incident last year, South Korea's Democratic Party leader, Lee Jae-myung, is taking extraordinary precautions as he campaigns for the upcoming presidential election. Clad in a bulletproof vest and addressing crowds behind transparent fortified glass, Mr. Lee is prioritizing his safety amidst a turbulent political landscape.

Last month marked the launch of his campaign, during which he dramatically revealed a white bulletproof vest under his jacket, symbolizing the seriousness of his situation. His supporters have expressed concern for his safety, urging him to stay behind protective barriers as he engages with the public. In response to the heightened threats, his campaign team has limited access to the candidate, granting only selected media representatives the chance to accompany him on his journey across the nation.

Lee's security measures stem from an assassination attempt earlier in January when he was stabbed in the neck by an individual posing for an autograph. This alarming incident has exacerbated fears of political violence, as the National Police Agency reports a significant uptick in online death threats directed at the candidate, with some instances being escalated to legal inquiries.

Threats against public figures in South Korea, though historically uncommon, are not unheard of. Notably, political figures such as former president Park Geun-hye have faced violent attacks, underscoring the potential dangers in the current climate. Political analyst Professor Yoon Taeyoung noted that the threat levels during this election cycle are markedly higher than those experienced in previous elections.

The use of advanced security measures by Mr. Lee may send a strong message about the increasing polarization and volatility in the country's political environment as the election approaches.
