I wouldn't say CZ is safe. We have law that says you can download music and videos for personal use. But you can't upload any copyrighted material. Which means that anti-piracy companies are going more after uploaders. But I know that huge Czech warez linking forum is hosted in CZ and it works there usually like, they will get letter from anti-piracy company (I think). There are links to threads which they want forum owners to delete. So owners will do and everything is okay again.
Also... CZ has some well known file hosts like hellshare, uloz.to or czshare. And uloz.to already said that they are not searching for warez on their servers. They will delete files only when they will get DMCA. But anti-piracy company already stated that they are gathering evidence to take care of uloz.to.
And yes, we are in EU and we are co-working with USA in many ways. But internet stuff is not one of it.
