No thread on this yet, so yeah.
ACTA (Anti-Counterfeiting Trade Agreement), to sum up, was a secretly-drafted agreement/treaty/thing between Japan, US, and the EU. It's goal is to criminalize copyright infringement and counterfeiting and allow for police searches, investigations, and follow-ups to copyright-infringement acts that have or MAY have been committed. Computer scans and other searches, for example, would be made on any kind of suspicion of pirating.
ACTA was leaked, however, and is causing all hell to break loose. I know that the Obama administration plans to use it as an executive agreement, putting as much of ACTA in place as possible without changing US law - and thus not requiring congressional approval. The Digital Millennium Copyright Act basically allows most, if not all, of the ACTA policies simply because the former is so vague and is currently a law.
If you want to see the document for yourself, I uploaded the leaked version to my site:
