March for half-truth?

Seems Sinn Fein have been marching for truth last weekend for some of the victims of the troubles (BBC story here).

Hypothetically, if you were Sinn Fein, and you wanted a process that would deliver truth for all the victims of the troubles, which would you think was more likely to succeed?

• a campaign to expose the evils perpetrated by “pro-british” forces, which ignores any harm done by republicans, or
• calls for truth about what happened to all the victims, with a promise to deliver the truth about the victims your own people had created. A promise backed up with actual delivery - starting, perhaps, with truth for the McCartney sisters.

Again hypothetically, if you just wanted a stick to beat “the Brits” with, which would you pick?
