There were fools who tried to bribe their way into freeing their brothers, only to be caught red-handed and thrown directly into prison without trial; the Emperor's Internal Guard Bureau is not an institution you can bribe;
Some had never witnessed the might of the Internal Guard Bureau and attempted to resist forcefully, only to be swiftly taken down. When it comes to force, the Internal Guard Bureau is unmatched;
Others tried to impeach the Internal Guard Bureau for harming the loyal and good, hoping to quell this storm, only to be dragged by the Emperor to face the wronged common people, subjected to their disdain while simultaneously being reprimanded for being either blind and deaf or intending to shield the guilty. The Internal Guard Bureau was ordered to investigate thoroughly, and indeed, the accusers were soon found to have issues themselves and were imprisoned.
After that, no one dared to intercede.
