The article author attempted to get the court order but could not find one. This is common when the order is made as part of an ongoing investigation, or else criminals could just watch for their names in PACER to know when to fire up the shredders.
Our system allows for challenging the government’s right to execute a search after the search has happened. And it isn’t open to random interlopers who think they’ve spotted a government misstep—you must have standing to challenge a search. The architects of this system didn’t want justice to get caught up in the equivalent of a GitHub pull request war.
Eventually the warrant will become unsealed and we can all inspect it.
Our system works on “trust but verify”. If the cops show up with a warrant they claim they is valid, you trust the warrant is valid, let them do the search, and later verify the warrant is real and that it was issued legally. Doing otherwise is a crime (obstruction of justice).
