Actor Kim Soo Hyun is facing backlash after hiring a forensic company with a controversial history to analyze messages central to allegations regarding his relationship with the late actress Kim Sae Ron.

During an emergency press conference, Kim denied wrongdoing and claimed that previously leaked KakaoTalk messages between him and Kim Sae Ron had been altered.

To support his claim, he said he submitted multiple chat records to a forensic firm.
"I submitted all the relevant messages — the 2016 and 2018 chats provided by the family, as well as my own recent chats with acquaintances — to a scientific forensic institution for analysis," Kim said. "

The result: The institution concluded that the person in the 2016 messages is not the same as the person in the 2018 messages."

Following his statement, internet users began scrutinizing the forensic company he used, uncovering a troubling past.

Reports allege that the firm has a history of analyzing statements in sexual assault cases, with many instances leading to acquittals of defendants accused of assaulting vulnerable victims.
In one case, the director of an orphanage was accused of sexually assaulting the teenage accuser.

The forensic analysis allegedly contradicted the testimony of the victim, and the accused was acquitted.

There was another case of a suspect who stood charged with molesting a sleeping complainant and, in a forensic report, posed the question of how the complainant could have remembered how she had been violated.

Past cases also reflect the company's work with children in abuse cases, sexual violence against the mentally disabled, and allegations of assault with coercive circumstances.

Critics have charged that the methods it employs too often undermines the testimony of the victim, and ethical questions have been raised about its involvement in criminal trials.

The revelation has fueled a public outcry, with many asking how Kim Soo Hyun can work with the firm.

This has led many social media users to express disgust, accusing the actor of associating with an institution that has been representative of alleged sexual predators.

There was no immediate response from Kim to the controversy over his forensic firm's selection.
