-- you make the large assertion that --
"Tacitus can be seen as a transmitter of second or fifth hand information, since there were no records from the 30s available to a writer in the second century"
-- and you have no evidence to back up that ridiculously categorical assertion about available data from the '30s in the early second century. All you have cited, when challenged, is fringe speculation on this at RatSkep with no ancient source to back it all up, either in connection with Tacitus in particular or with early second-century chroniclers in general.
As it stands, this is a categorical assertion of yours with nothing other than pure speculation by amateurs at RatSkep behind it. There is no ancient cite shewing just what Tacitus and other second-century chroniclers had at hand from the '30s of the first century, c.e. It is past time that you either concede that your ludicrous assertion is based on fringe speculation only, or that you withdraw the assertion altogether.
There is extant evidence relating to Tacitus's chronicling methods, BTW. Tacitus himself specifies that he bends over backwards always to make a distinction between hearsay and personal accounts -- and he does not reference hearsay in his account of the fate of the despised founder of Christianity during the Tiberius years.
