You can buy almost anything on the Internet auction site eBay, but there are certain things that, as one Annapolis man learned last week, you can't sell there: among them, pirated pornographic videos.</br></br>A month-long investigation by a task force of the Annapolis Police Department, the U.S. Secret Service and U.S. Postal Service inspectors culminated on March 9 with an early morning search of 48- year-old Hari Prasad's apartment in the 1000 block of Primrose Road.</br></br>Police said a California resident bought two pornographic videos from Prasad on the Internet site and, when they arrived, was dismayed to find not originals but copies dubbed on generic tapes.</br></br>The buyer tipped off authorities, and last month Detective Pete Medley of the Annapolis Police Department keyed in Prasad's e-mail address and ordered up a few of the titles.</br></br>Authorities say that when they closed in on Prasad's home, at 6:30 a.m., they found what they were looking for. Among the evidence collected were 78 copy-protected original videos, 360 illegal copies, 120 blank VHS tapes and ledgers documenting the eBay sales.
