Pretty certain that if a US criminal, or suspected crim, owned a house in Ireland, the FBI couldn't just raid it looking for incriminating evidence. They need the permission of the Irish authorities. Same goes for magnetic zeros and ones.
Looking at the Dotcom case, yeah they pretty much would - with help from Irish's version of GCHQ, and police officers duped into believe that it's a legitimate operation because GCHQ ordered it. And when it's found that GCHQ acted in a criminal manner, the Irish version of Shon key and his scumbag government will pass laws retrospectively making their actions legal after all (even though they used guns to commit a violent crime!)
