High court backs cops who barge into homes

A recent U.S. Supreme Court case made it harder to sue police for barging into a home and provoking a shooting.  The case rejects the provocation rule wherein police can be sued for violating a victim's constitutional rights against unreasonable searches if they provoked a confrontation that resulted in violence.  The ruling holds that police cannot be held liable for injuries they caused as part of a search unless the search itself is unreasonable.
