So federal criminal laws should govern the content of material published by private individuals not under contract with a government agency? Wow. Should they government be doing this in the name of freedom?
Publishing “Full text of case” when publishing SCOTUS cases menas you are publishing the FULL text of the case. If you state that on material that you have deliberately REMOVED text from, and altered in other ways....
Yes, there should be and in fact IS legal penalty for doing things like this.
There is also a push in the Government Printing Office for Digital Authentications of Governmet Documents, and that includes SCOTUS cases which are the Law of the land.
