When the scandal first started, I suspect many people were afraid that President Park might commit suicide (which has happened frequently in such scandals in Korea).
President Park is desperately trying to extend her stay as President. When her term ends, she will be indicted and probably go to jail for a long time.
Since she is surrounded by guards, they should be able to stop any suicide attempts.
It could take months to get rid of her.
