It's a sign that you're getting a little too concerned with secrecy when you start hiding things from yourself. From

Jesselyn Radack at Kos:
At a hearing last month, prosecutors in the case against Pfc. Bradley Manning noted that they didn't receive [important emails from the judge and defense] but could not explain why. Chief prosecutor Capt. Ashden Fein said at a hearing Thursday that the messages had been "blocked by a spam filter for security." However, it fell to defense attorney David Coombs to explain precisely why the e-mails about evidence issues in the Manning case never made it.
"Apparently, they were blocked because the word 'WikiLeaks' was somewhere in the e-mail," Coombs said.
Because they didn't get the emails, they didn't turn over documents to the defense that they were supposed to turn over, or explain why they didn't want to turn them over. The fail is bad enough, according to Radack, that Coombs feels entitled to move for dismissal of all the charges.
