Evidence against Shincheonji has surfaced??

Then you should make an official announcement clearly.
Stop just playing media games and state exactly what data was used, how it was verified, when and how they joined, and what the true nature of "Ban-Bun-Sin" (Half-Division-Faith) actually is.

If you just make a vague announcement and drop hints, Kim Ji-yong will get slammed tomorrow for trying to divert attention during the hearing, and your approval ratings will take an express trip to rock bottom.
Mr. Kim Cho-kyo.
