This trial will be a politically motivated kangaroo court. It will be driven by the Batarians and empowered by Alliance officials wishing to avoid war with the Batarians as preperations are made for the coming invasion.
I think it will be based purely on any charges the Batarians can come up with, although I acknowledge the possibility that they may receive help from indoctrinated individuals that would say anything to get rid of Shepard for the Reapers.
Many of the charges listed in other write ups in this forum would not come into this trial because they are not common knowledge. Shepard aiding Garrus in the vengence killing of Sidonis for example. Upon the Normandy's departure, CSEC did not have more than a bullet to tell them anything about the killing. Garrus has had plenty of time to disassemble and space that weapon even if someone actually figured it out.
Numerous other charges could not be used as they were performed as a Council Spectre.
For what remains, I think that Shepard will have made a deal before going into court about what he would be willing to talk about.
Issues denoting possible guilt would include:
- Issues mentioned in Shepard's after action report. This may be used as a confession.
- Any video of Shepard in the Batarian prison that might be recovered if it was stored far enough underground on non-volatile media.
- The incomplete warning to the Batarians if it was sent. If Shepard is Paragon, he might be able to turn this to his advantage.
- Indoctrinated individuals that escaped the Project in escape shuttles if they can be identified and found.
