Erik Barnett, assistant deputy director of ICE said told the Guardian that the agency will actively target web sites that are breaking US copyright laws even if their servers are not based in the US. According to Barnett, all web sites that use the .com and .net TLDs are fair game and that, since the Domain Name Service (DNS) indexes for those web sites are routed through the US-based registry Versign, ICE believes it has enough to "seek a US prosecution".
According to the Guardian, ICE is not focusing its efforts just on web sites that stream dodgy content but those that link to them, something the newspaper claims has "considerable doubt as to whether this is even illegal in Britain". It points out that the only such case to have been heard by a judge in the UK was dismissed.
Barnett said, "By definition, almost all copyright infringement and trademark violation is transnational. There's very little purely domestic intellectual property theft."
