Many people are contending that this affair is entirely in-house, and shoudl be handled as such. Sadly, that is not true. We have dead Mandalorian NPC's, as Larraq has said many times that the civilians involved were of many nations. Our dead PC, [member="Aaralyn Rekali"] is a Mandalorian, whos' father is a Mandalorian. She was also a Jedi. And yes, she was actign a republic ally of sorts in this invasions. However, her father, who has leadership within the Mandalorians, is unlikely to stand for a closed trial with no oversight or involvement from their people. That is the political, IC reality of this situation.
If we are truly serious
In the spirit of full disclosure, my character in the invasion, Vorhi Alestrani, is targeting Ali Hadrix based entirely on the hearsay of a bunch ghosts screaming in his ear. His actions are those of a lone vigilante, and don't reflect much on Mandalorian or Republic matters. However, his actoisn resolve in the thread in question.
However, as someone who has done lots of inter-faction diplomacy for other major factions, we need to show some level of deference to the Mandalorians. Failure to do so will bite us in our backsides quicker a than a rottweiler on a kid with steak in his pocket.
