Guards Protecting SCO Execs After Threats

SCO Group Inc. said bodyguards were protecting its top executives after the software maker received death threats for claiming to own programming code in the Linux operating system and demanding fees from users.

Backers of so-called open-source software such as Linux, whose code can be modified by users, have denounced SCO since it sued IBM Corp. in March for copyright infringement. SCO is seeking as much as $50 billion in damages from IBM and has said it would bill companies using Linux.
