No one is saying that *all* random data is incompressible - in fact, some random samples are *very* compressible. A single sample of random data might look very much like the text of "A Midsummer Night's Dream" (especially if your method of choosing the random sample was to pick a book off a library shelf). But unless otherwise qualified, a claim of being able to compress random data is taken to mean any and all sets of random data. Anyway, that's going to be my only contribution to this thread.
