WASHINGTON (AP) - The Obama administration's extraordinary decision to point fingers at North Korea over the hacking of Sony Pictures Entertainment Inc. could lead to a courtroom spectacle if charges are ultimately filed against someone without ties to the isolated country.

WASHINGTON (AP) The Obama administration's extraordinary decision to point fingers at North Korea over the hacking of Sony Pictures Entertainment Inc. could lead to a courtroom spectacle if charges are ultimately filed against someone without ties to the isolated country.

Legal experts say potential complications illustrate why federal authorities rarely announce they've solved a case before an arrest.

U.S. officials for weeks have been emphatic blaming North Korea for the hack attack, citing similarities to other tools developed by the country in specific lines of computer code, encryption algorithms and data deletion methods.

The Obama administration asserted its certainty again last week, announcing a new round of sanctions against North Korea that officials said will be just the first step of retaliation.
