That's really the most important document, by far.  It has the justification -- or the explanation of probable cause -- for the search.  

Meantime, the insane attacks on Magistrate Judge Reinhart have led to renewed calls for extra security for judges.  From Reuters:

The federal judiciary is renewing calls for Congress to pass a stalled bill aimed at bolstering judges' security after the magistrate judge who signed off on a warrant authorizing an FBI search of Donald Trump's Florida home became the subject of online threats.

The chair of a key judiciary security committee and the president of the Federal Judges Association in separate remarks on Thursday pushed for the bill after U.S. Magistrate Judge Bruce Reinhart became the target of a wave of violent, anti-Semitic threats.

That legislation, the Daniel Anderl Judicial Security and Privacy Act, was named for the deceased son of U.S. District Judge Esther Salas, who was killed in an attack at the New Jersey judge's home in July 2020 by a disgruntled lawyer.

That bill would allow federal judges to redact personal information displayed on government websites and bar people and businesses from publishing such information online if they have made a written request not to do so.

The Senate Judiciary Committee advanced the bill on a bipartisan 22-0 vote in December, but attempts to quickly pass it unanimously in the Senate have been blocked by Republican Senator Rand Paul of Kentucky, who says it should also cover members of Congress.

U.S. Circuit Judge Richard Clifton, the president of the Federal Judges Association, in an interview said with time running out in the current Congress to pass the bill, judges are being encouraged to contact their local lawmakers.

"The news of the last few days underscores the concern that we have," said Clifton, who former Republican President George W. Bush appointed to the 9th U.S. Circuit Court of Appeals.
