@revelette3,
It's a shame that an entire political party is prepared to block investigation of such an incident - even if they know the likely outcome.
If the investigation produced a biased report, then they would be able to tear it apart in public and discredit the authors (presuming they are organised enough to keep track of the testimony and prepare their own analysis prior to the reports release). But they appear to both fear that....and by opposing it, support corruption (of the nature of particular party members being allowed to get away with incitement, and of not being held accountable for political actions)
