(2) Copying or otherwise obtaining any program or data contained within a computer.

In some situations, such as with California, if a state has dealt directly with a particular category of computer crime within the context of a larger encompassing computer crime statute, we have included in our statutory analysis a cross reference to the relevant subsection of that state’s statute. We have denoted states that are also listed in our general computer crime statute section with a ‘*’.
