I'm not completely sure I understand the consequences of this court decision, but its seems to suggest that police can use their authority to search under the probable cause standard in the 4th amendment not only for items related to the accusation that one has committed a crime, but for items that will allow the prosecution to build the case against the accused that involves others not related to the crime.
Evidence can be obtained that can "impeach witnesses and respond to potential defenses."
This seems to me to be a problematic expansion of search and seizure, but this is beyond my expertise.
