Basically, they are outlining a slicker way to deceive.
Hypothetical scenario: a post IED-detonation firefight in Iraq results in a female civilian being killed in the crossfire.
the group will keep on file in its Philadelphia national office a copy of each testifier’s military service record, known as a DD-214 form
They will find an IVAW shill with a military service record who can plausibly claim to have been in Iraq at the time and who is willing to tell a fanciful story about the incident.
Vasquez’s committee—made up of a team of twelve veterans around the country—will reach out to members of his or her unit for corroboration
They will find one person from his unit who will say that the IVAW shill was in their unit at the time specified. Maybe the contact will also say that he had heard about the incident or was there for it.
That other veteran may not agree with or even know what the IVAW shill's recollection is, but that won't matter.
A network of journalists currently in Iraq will reach out to Iraqi civilians in the relevant cities and towns for independent eyewitness accounts.
Journalists in Iraq will contact local terrorist sympathizers and get their fanciful version of what occurred.
Finally, IVAW will file Freedom of Information Act requests with the Pentagon for relevant corroborating or refuting information
They will get paperwork from the DoD that will tersely document the incident.
Then the IVAW shill will get up on stage and say "I heard my fellow soldiers tell me of a firefight in which a soldier was ordered to shoot an unarmed woman - the officer kept shouting: 'Get her! Kill her!' until someone blew her away. I later found out that she liked to make origami puppets for sick children in the local hospital and dreamed of being a talk show host. Those dreams are now gone forever."
And when questioned, IVAW will produce a DoD form referring to the incident, a DD-214 form showing the IVAW shill to have been present in Iraq on that day, a partial, edited transcript of another soldier attesting that the DD-214 form is accurate, and finally some long colorful accounts of all the lurid details in the IVAW shill's testimony from local Iraqi terrorist sympathizers.
even though this dossier would not stand up to any minute scrutiny, it looks and sounds impressive to a journalist, it gives any journalist more than enough plausible deniability, and it allows IVAW to say: "This is all documented by the US government and eyewitnesses!"
