"Article the sixth... The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
Police under the US Constitution have to go before a judge and court and make an Oath under perjury of law describing the items to be seized. There has to be a justification and supported by affirmation meaning evidence and supporting facts. In the case of the building that was seized it was operating a perfectly legal business under state law. It had the necessary licenses and permits. There needs to be a direct challenge against this type of extra-judicial seizure in the US Supreme Court as it's a clear challenge to the entire operation of the rule of law and legal system.
