Mary was suspicious of her neighbor, whom she thought was involved in selling illegal drugs. One day, Mary arrived at her apartment and saw a large paper sack tied up with string in front of her neighbor's door. She took the bundle into her apartment, opened it, and discovered it was full of cocaine. She called the police and the neighbor was arrested. The neighbor's lawyer claimed the evidence had been illegally obtained because there was no probable cause to justify opening up the paper bundle. What do you say?
