one oddity of Carter Page FISA release information, including Horowitz report, has been redaction of exact dates. Why? What is ostensible reason? And what is real reason? Horowitz redaction gives an interesting nugget. 
2/ @seanmdav has pointed me to dates in Horowitz version presently online at DOJ. These dates were redacted in the first Horowitz version (which I downloaded in first minutes.) For some reason, they were subsequently unredacted. Strange.
@seanmdav 3/ I deleted some tweets in which I was trying to figure out these dates, as they were irrelevant. Nothing embarrassing in the deletions, but I prefer to be as accurate as possible and there was no need to keep them.
