This is a role play situation. Deal with it in role play. If you can't carry on with playing your character or defending his stance among such circumstances, no one is asking you to do so.
This is a game, this is not real life. Why should we stall the investigation if we have all the needed evidence to piece everything together? Obviously we're not working with an entire division of bureaucrats in reality, for them there may be a need for more time, but we are in fact half dozen of real life people discussing something in a limited sphere, which are game mechanics and server rules.
Your character feels insulted? By all means, he has the right to do so. Feel free to voice it in-character, with the limited tools he or we have available. Just don't be surprised if people iRP take offense in what you said iRP.
You're feeling personally insulted? Your mindset is wrong about the whole situation then and you have no right to derail a role play scenario with OORP terms since no one here is actually after the Congress. We're people playing a game among boundaries, something like a deck of cards.
Please don't resort to taking this situation out of character when no one of the RM is doing so.
