EYE AT THE KEYHOL The Supreme Court again has narrowly interpreted privacy rights, ruling on Tuesday that people who visit someone's home only briefly or to do business do not have the same protection against police searches as do overnight guests. The ruling - that such visitors have no reasonable expectation of privacy - no doubt will give comfort to those who want to expand police rights to search suspected criminals. However, it further erodes the widely held expectation that one's home is one's castle and an inviolable bastion of privacy, and that those protections extend to one's invited guests. In a 6-3 vote, the high court reversed the Minnesota Supreme Court and reinstated the convictions of two men for trafficking in cocaine. In a 5-4 vote, the justices made a controversial distinction between residents' right to privacy and that same right as it applies to visitors in a dwelling "simply . . . to do business." In a ruling just eight years ago, the court found that overnight guests have an "expectation of privacy" protecting them from warrantless searches and arrest as proscribed by the Fourth Amendment. Tuesday's ruling makes it clear that short-term visitors do not share that same privacy right. The case arose in 1994 after police saw the defendants enter an apartment in Eagan, Minn., and observed them through closed venetian blinds packing a white powder into bags. They were arrested a few hours later. Because the men were in the house for a relatively short time to conduct business, the court ruled they had no standing to complain about an illegal search. That is the argument made by the Minnesota prosecutor, who hailed the ruling as a victory for public safety advocates and a much-needed tool for police in their fight to keep communities free of drug dealers and other criminals. Tuesday's ruling opens to question a wide range of possible scenarios that might wind up in court. For example, would the two visitors have shared the host's privacy right if they were blood relatives or close friends - as well as criminal associates? How long must a visitor remain in a home before he legally can share the host's protection from unreasonable searches? We eagerly await a Supreme Court ruling to clarify these troubling questions. Otherwise, we share the fear put to paper by Justice Ruth Bader Ginsburg: that homeowners who invite guests into their homes - for legal or illegal purposes - thereby "increase the risk of unwarranted governmental peering and prying into their dwelling places - ---
