LAS VEGAS — Kayvan Kazemi spent the night before his police entrance exam studying the gambling tables.
The 24-year-old Long Island, N.Y., officer candidate lost about $400 in the casinos before calling it a night. But nothing he did violated the law or disqualified him for a spot in the Las Vegas Metropolitan Police Department academy. It was just a typical night in Vegas, where Kazemi is still in the running for a job. And Lt. Charles Hank, the department's personnel chief, says there are worse examples of pre-test preparation.
