And it's an administrative nightmare....Somewhat equivalent to the key 
management problem with one-time pads...lets take 1M works to be protected 
against "bad stuff" by 1000 Users (multiply by 1000 for Britney) that's 1B keys 
that have to be tracked for how long? A hundred years? The laws cannot be 
selectively enforced. .002 may be right about the need to reduce copyright 
term. As more stuff gets copyrighted the administration of it for long periods 
is too much of a burden. As with any Kalman filter if you don't flush it out 
once in a while, you get garbage in the end.

And the post first sale doctrine. But who can expect greedy bastards to 
understand the consequences of their actions...

Only if you kept a detailed record....invading privacy..these people and 
Congress do not seen to understand how much of an administrative burden they 
want to impose on society. It dwarfs the criminal system for a "civil" action.

They have a defense and he doesn't

Until the P2Ps reverse engineer what's going on and start a counter counter 
measure activity to prevent them from finding the networks, getting the info or 
they just start trading lists of suspicious scanners.

I think that the RIAA, MPAA objective is beyond that. When someone infringes 
and makes an illegal copy they have violated the law. When I buy one of their 
copies, I have NOT. That copy is mine to do with what I wish. I may make ALL 
fair use of it that I can. I may sell it. I may copy it. I can space, media, 
time shift or throw it in the trash and someone else can acquire it. The law 
absolves the innocent...but with the RIAA MPAA, there are no innocents if you 
have infringing material.

Probable cause in civil , reasonable doubt in criminal...but there must not be 
a double standard in the law. Which this introduces. The perversion here is 
that the act can be procecuted under different scales-Lady Justice must now 
balance two scales. Lady Justice being blind is now directed which one to use 
but cannot assess which was the right one.

Only if there is fair use....the LOC has been tasked to look at the availablily 
of other media. So one can copy from a VCR but not a DVD because the latter 
circimvents but the former doesn't. They confuse the media with the message. 
But that's the situation with the LOC.

What if they put their own finger prints on? THe other problem here is 
prosecution of innocents. Remove the finger print and substitued another. DO we 
want JackBoots and the Internet Jackboots appearing at someone who has been 
"framed"
