Anthony Davis operated a computer bulletin board system that permitted users to send and receive e-mail, access the Internet, and download software. Davis’s system had one attribute that distinguished it from, say, AOL. It specialized in pornography. Alerted by an anonymous tip, the Oklahoma City Police Department obtained a warrant to search his premises for “equipment, order materials, papers, membership lists and other paraphernalia pertaining to the distribution or display of pornographic material.” During their raid, the officers seized computer equipment that contained 150,000 e-mails in electronic storage, some of which had not been retrieved by the recipients. Alleging that the e-mails had not been included in the warrant, Davis filed suit against the police officers for violations of the Electronic Communications Privacy Act. Does Davis have a valid claim?
