I'm thinking that instead of harvesting what we find, (unless it is a site that like us, verifies identity) we should make an effort to get the people themselves to come speak here, if we can. I think that in this situation where when people knew something, and what they knew, and who they shared it with, all are critical elements and it is easy for someone to evade responsibility and try to say something that isn't true and then use that as a fact. Likewise letters and so one, without verification it is easy to make up fakes.
