Speculation, but perhaps this is because they want to wait until the victims have passed? I suppose in that case though, they could just redact the relevant information, which to me implies a cover-up for political reasons? This feels kinda like I'm going a little of the rails, but in that situation, it only seems smart to cover that up for so long if it also implicates someone revered by the public, or I guess someone that laid out important ideological viewpoints they worried would be undermined in a dangerous way by the release of the info.

Sorry for the conspiracy theory, hope its not crackpot lol
