UK ISPs not cooperating with law enforcement

I haven't checked the law since the Patriot Act was passed. Prior to
that, however, in the U.S. the law *prohibited* communications carriers
from giving certain information to the government without a warrant --
but they were free to give it or sell it to anyone else. see (c)(1)(A)
