Do let us know how your portscans of US military networks goes...

Are you one of them?

IANAL, but I do know that last year a federal court in the First US
District (Washington D.C. and surrounding area, as I recall) ruled
that scanning was NOT illegal. It is a court of record and, until
reversed by a higher court, stands a a precedent in that district (but
not others). As far as I know, there has been no higher court ruling.

That said, I guess if you are scanning a system in that district, you
have no problems. But you may have problems if the system(s) scanned
are elsewhere, though there is no specific law on the subject. The
action reviewed by the court was under federal anti-hacking laws which
might be construed as covering port scanning. The court held that they
did not.
