I find it interesting, though not in the least surprising, that the above quote assumes that all users of steganography are terrorists. From this position it is a small step to the position that all individual civilian users of strong/unescrowed cryptography are terrorists.
I fully agree. Go one step further: Every civilian who sells at ebay, puts a picture on the auction web page, and doesn't take care that this picture can't be reported falsely positive by some arbitrary software by any company wishing to be in the headlines, can be considered being a terrorist as well. So, simply, everyone selling on ebay with a picture (oops, I did as well), is in danger of being considered as a terrorist. You never know what next month's stego detection software will pretend to detect in one's picture. And as we know, the US convicts terrorists at those lawless military courts. Gee, I was never aware how dangerous it is to sell on Ebay. (Any idea how to make a picture reliably stego free against *any* stego detection software?)

Set all the pixels to the same value. Of course, you can trasmit a couple of bytes of information that way, and some more with the image size. So, I hereby decree that all pictures will be 256x256 pixels, 8 bits per pixel, all bits set to 1. Guess we need to mandate the compression method, too, lest you transmit a few bits by choosing it. So, uncompressed TIFF format. Of course, there's massive benefit to this. Now all pictures can use the same URL. Consider the massive bandwidth saving caused by caching. What a benefactor I am.
