Does this make sense to you? It doesn't to us. There is no definition of what is "indecent," and the federal government has, in the past, shown a definite willingness to use such broad laws very selectively to punish individuals they don't like. It doesn't matter if you manage to get the law declared unconstitutional or even manage to be found not guilty. They still punish you by forcing you to spend more money than you have on lawyers, and you most likely spend quite a bit of time in jail waiting for your trial and appeals.
Don't let the "interstate or foreign commerce" condition fool you. The federal government has historically always claimed that if you use a medium capable of being used in interstate or foreign commerce, then you are effectively engaged in it, regardless of what you are actually doing.
The text of the first part of section 502 follows:
SEC. 502. OBSCENE OR HARASSING USE OF TELECOMMUNICATIONS FACILITIES UNDER THE COMMUNICATIONS ACT OF 1934. Section 223 (47 U.S.C. 223) is amended-- (1) by striking subsection (a) and inserting in lieu thereof: `(a) Whoever-- `(1) in interstate or foreign communications-- `(A) by means of a telecommunications device knowingly-- `(i) makes, creates, or solicits, and `(ii) initiates the transmission of, any comment, request, suggestion, proposal, image, or other communication which is obscene, lewd, lascivious, filthy, or indecent, with intent to annoy, abuse, threaten, or harass another person; [...deleted for space...] or; `(2) knowingly permits any telecommunications facility under his control to be used for any activity prohibited by paragraph (1) with the intent that it be used for such activity, shall be fined under title 18, United States Code, or imprisoned not more than two years, or both.'; andIt also defines a few more similar offenses, and exceptions that are apparently intended to protect your telephone company, America Online, and the like from being responsible for what you say or send, but they are written in such a convoluted way that I still haven't figured out what they actually say. If you want to see all of section 502, you can get it here, and you can get the entire new telecommunications act from the House of Representatives at ftp://ftp.loc.gov/pub/thomas/c104/s652.enr.txt. It's about 400kb long, so be prepared to wait!
