from a press conference point of view I guess, the entire presentation has to be made in the form of soundbites, one-line plus image of cute kid slides and a nice press kit with the article already written :)
as already mentioned, ply them with alcohol and write the whole thing for them - the editor will of course randomly snip things, but I have found that one can achieve as high as 60% accuracy by this method
There is a foolproof method followed by many of us these days -- it's called "playback for fact-check" -- we send the final copy for approval to the interviewee to avoid any discrepancies due to misinterpretation. And, all interviewees/featured can demand that the journalist show them the EDITED draft of the article before it goes to print. Just that the interviewee needs to be prompt in responding with any corrections needed, so that the editorial process doesn't get delayed. But that avoids most problems.
However, it is possible mainly in the case of magazines/websites/weekly publications/supplements -- I am not sure if it works for dailies.
