i don't think that the warrants are sealed to brad, cisco and their attorneys--- only the public.
LE sealed the last 2 SWs served on jason young's family residences where he had been staying (younger sister and mother's houses ) on feb 14th, 2008. the youngs got copies of the SWs as they were being served and their homes searched.
they are free to discuss those warrants publicly if they choose. they have chosen not to talk about the contents of the SWs and probable cause linking jason to the murder.
the SWs remain under seal from the public. there may be more that we don't know about in the murder case of michelle young.
TO add to Saint's reply, the warrants are sealed until an inventory is made by LE, and then it can be made available to the public.
