Legal Question in Criminal Law in California

Re: search warrent

You have no "right" to be present during a search, but you may be allowed to and/or detained on the premises during the search.

The form of the warrant won't necessarily say it's a "blanket" warrant. In fact, you may not see the warrant, as there's no requirement they show it during service. They must leave a property receipt for anything seized, but not the warrant.
