If it’s a search warrant, A copy of the sworn affidavit must be given to the suspect. The government has to ‘show its hands’, to some extent.
THey rarely let you read the affidavit....largely because it identifies the complainaint ion most cases.
( for example: Ex wives are known to file false affidavits for search warrants...exercising their wiles on LEOs sometimes.)
If an officer knocks at our door, a rare thing, I always do not allow them into the house. I go out to the porch and speak there.There are all sorts of DEI shenanigans going on right now.
