Hi OBE,
Keeping warrants sealed means something to me because of what LE has to do to GET the warrant in the first place.
"An application for a warrant must be supported by a sworn, detailed statement made by a law enforcement officer appearing before a neutral judge or magistrate. The Supreme Court has said that probable cause exists when the facts and circumstances within the police officer's knowledge provide a reasonably trustworthy basis for a man of reasonable caution to believe that a criminal offense has been committed or is about to take place (see Carroll v. United States, 267 U.S. 132 [1925]). Probable cause can be established by out-of-court statements made by reliable police informants, even though those statements cannot be tested by the magistrate. However, probable cause will not lie where the only evidence of criminal activity is an officer's affirmation of suspicion or belief (see Aguilar v. Texas, 378 U.S. 108 [1964])"

I know some warrants were served at places that we would customarily see them served, like their home. Probable cause is needed as far as I know, which is not the same as reasonable suspicion(someone let me know if ai am wrong here)
I think they needed very good, strong reasons including proof of certain circumstances in order to get the warrants. I think keeping them sealed is to protect the case, it could be customary in AZ but then why release any. Also LE has continually said they do not want to compromise this case, perhaps there is information in those warrants they cannot safely let out now. I am just much more on the side of "it means something" right now.
Also, Dr. Know posted about this a few posts up, I do have the same feelings as Dr. Know regarding the warrants.
