> people who tell you where you can find drug dealers. ... people who get paid to direct you to the nearest drug dealer, and only to drug dealers, organized by type of drug, quality, and potentially even with a rating system. These sites are more than just innocent passers-by. They aren't the "drug dealer," but they aren't just a dude on the street who bought drugs that one time and might know a guy. Where the line i…
> But where some say "they're identical to Google," > I personally see a very large, obvious distinction. If Google's 'Product Search' links you to a website where you identity is stolen, is Google liable? Should the government 'crack down' on Google?
The parent poster is right under the current law (despite the downvotes). Google Product Search has numerous non-infringing uses, whereas a site that exists to do nothing more than link to pirated content will have a lot more difficulty in showing they aren't contributing to copyright violation.
The biggest, most recent case involving this was Grokster vs MGM [2]
The court found:
We hold that one who distributes a device with the object of promoting its use to infringe copyright, as shown by clear expression or other affirmative steps taken to foster infringement, is liable for the resulting acts of infringement by third parties[3]
Wikipedia has a good discussion of the ruling:
Justice Ginsburg, joined by Kennedy and Rehnquist, claim that "[t]his case differs markedly from Sony" based on insufficient evidence of noninfringing uses. On the other hand, Justice Breyer, joined by Stevens and O'Connor, claims "a strong demonstrated need for modifying Sony (or for interpreting Sony's standard more strictly) has not yet been shown," primarily because "the nature of [...] lawfully swapped files is such that it is reasonable to infer quantities of current lawful use roughly approximate to those at issue in Sony.[3]
The key point is * non infringing uses*. The court needs to be convinced that they exist, and this occurs on a case-by-case basis.
You (and I) may not like this law, but that is how it currently is being interpreted.
IANAL, etc.
