He's trying to clear his friend of false accusation but in Korea, where private detectives are illegal, there are limitations.

The government is in support.
Just over a week ago, the police opened a blog that updates information on legalizing private investigation.
It expects some 4-thousand jobs to be created, and hopes private investigators will help solve insurance fraud cases, find missing children and more.

"If access to an individual's private information is given to the private sector, that in itself raises the possibility of privacy violation. Realistically, only the rich can hire private detectives, so it creates an imbalance of information in judicial proceedings."
Citizens are also divided in the debate.
"I'm against it because I'll feel like I'm being watched."
"I think it's OK because they'll solve cases that the police can't solve."
Facing tense debate, bills to legalize private investigations are stalling.
It seems that preparation against the potential side effects, like training and supervision, is necessary to break the impasse of the National Assembly.
