First off to answer the question, we or at least I view cycling (Pro Racing) through the Cyclist (Racers), what they do in the race and their interviews on the race/team tactics. If we hate a cyclist it is most likely due to their lack of backing up their word or expectation based on their announced expectations of a race or season, then there is getting banned for any reason.
Did Paul overstep the line? Well if he did not would you say he didn't ask the appropriate question or have the testicles to ask the real questions? As an interviewer/reporter he has the right to ask. Is it right to attack a cyclist? Well if you have evidence or extra information on a situation it is the reporters duty to get to the bottom of it. Sure it could of been done a bit more tactically but he did it and its done. I would still at this point after the events have transpired for more information on the matter from those two parties (not the peanut gallery, aka forum guess bots).
As for books, when will the next cycling related book come out that's not you know what related?
I'd like to see a book on a cyclists career and team/race tactics used throughout, how it failed/succeeded, possibly some antidotes on riders personalities/failings/jokes/etc...
