You've nailed it.
This is a "lose-lose" situation for the MSM.
If they don't report it, it speaks volumes about how they censor the news to match their ideology.
If they do report it, it will be an obvious about face on all their previous coverage.
They will probably end up reporting it, but only after suffering the damage...the worst of both worlds for them.
If they report it at all, they are going to take the approach that the BBC and Drudgereport’s link to the Globe took.
They are going to report the hacking, but not what the emails reveal. In the Globes case they quoted a Global Warming establishment guy repeatedly saying “the bulk of evidence...” completely disregarding that these emails call into question the validity of that “bulk of evidence”.
