Well, it might be ONE answer, but not necessarily the definitive one.
First, there is no detail in the first post that helps to evaluate the circumstances of the first search. I can conceptualize a number of scenarios that would make the first search good, or bad - depending on the details.
Second, the nature of the law in different states orfederal circuits might come in to play.
In general, if the first search was good (based upon probable cause, consent, etc.) and they discover something unlawful and outside the scope of the first search, they can go and obtain a search warrant for that.
So, if we expand upon your protective sweep idea, and in the process of the sweep they find a meth lab in the kitchen, they can freeze the scene and return with a search warrant.
In any event, we can squeeze scenarios to fit the desired end result ... the question is, what are the details here? What happened?
