"There is no federal shield law"
Not even former or sitting presidents are protected.
> The search warrant, signed by Marion County District Court Magistrate Judge Laura Viar, appears to violate federal law* that provides protections against searching and seizing materials from journalists. The law requires law enforcement to subpoena materials instead. Viar didn’t respond to a request to comment for this story or explain why she would authorize a potentially illegal raid.
It can appear as a can of tomatoes being consumed by Andy Warhol himself. It doesn't change the fact there are no shield laws in Kansas or the US for journalists.
>...it shall be unlawful for a government officer or employee, in connection with the investigation or prosecution of a criminal offense, to search for or seize any work product materials possessed by a person reasonably believed to have a purpose to disseminate to the public a newspaper, book, broadcast, or other similar form of public communication
... followed by a bunch of caveats about cases in which it is acceptable to seize documents. I'm not a lawyer, but that sounds to me like a federal law protecting journalists. Whether or not it was violated in this case remains to be seen.
