Cool, say you've done so despite obvious issues (no microSD is over 1 TB, since TrueCrypt is no more there's no obvious trusted encryption software for that sort of thing, then there's borders, being on a security camera at a post office, etc).

Which address would you ship it it to so it reaches Wikileaks?

So you need to send two microsds, fine. You'll probably want to use something more trustworthy like luks with a detached header and a largeish offset. Finally, drive some tens of kilometres and throw it into a mailbox somewhere in the fields at 3 o'clock.

I don't know what address wikileaks has, but then again I never tried to contact them.
