I enjoyed it while it lasted, but the CJR was clearly frivolous, : the T-Shirt was clearly not a munition, IMHO, and that's that. Write up : the experience, post it on the web somewhere (I'll provide a space if you : need it), and call it a day. I am afraid that I have to disagree with this. The T-Shirt, or rather the cryptographic software that is disclosed by the wearing of the shirt, is just as much an item that falls within the ITAR's definition of an item on the United States Munitions List as any other cryptographic software. The only way that wearing the T-Shirt without a license from the censors in the Office of Defense Trade Controls would _not_ be a violation of the ITAR would be if either (i) the censors, in their totally arbitrary discretion issue a commodity jurisdiction determination that the T-Shirt is not an item on the United States Munitions List or (ii) the ITAR are determined to be unconstitutional. There is no exception in the ITAR for printed materials. The fact that in one case a book got a favorable commodity jurisdiction determination and a CDrom did not is not evidence to the contrary, it just shows how completely arbitrary the the ODTC's commodity jurisdiction determinations are. Nor is there an exception in the ITAR for T-Shirts. Of course the cryptographic software on the T-Shirt is constitutionally protected, so it is not, in the constitutional sense, a violation of any law to wear the shirt in the presence of a foreigner. But then it wouldn't be a violation--in the constitutional sense--for me to disclose that cryptographic program to the foreigner who wrote it in a communication over the internet. And I assure you that when I have discussed their encryption programs with foreign authors by e-mail I have always been very careful not to disclose their own programs to them. It may not have much to do with cryptography, but it has everything to do with the First Amendment to the United States Constitution, that speech in any form, even on the backs of T-Shirts, is protected. Remember there is a leading First Amendment case involving a T-Shirt inscribed with the immortal words: ``Fuck the Draft''. Even if requiring one to obtain a license, or a non-obstat, from the censors before communicating cryptographic software to foreign persons by publishing that software were not to be held unconstitutional per se, a licensing scheme that does provide any way to get a license for a T-Shirt or a book is clearly unconstitutional. The government cannot refuse to license speech simply because the medium on which the speech is affixed is frivolous. And the message communicated by the T-Shirt is clearly political, so arguably that message is _more_ protected by the First Amendment than the PGP program on a floppy disk. -- Peter D.
