The Los Angeles Police Department said Wednesday that it spent about $1 million on overtime for officers and civilian personnel handling the Michael Jackson memorial. The number is lower than the estimated $2.5 million the department expected to pay for the event. The crowds were much smaller than anticipated, and about 1,000 officers of the 3,200-officer deployment were released early. It's still unclear what the city's total costs will be, including traffic control and street services. It's also unclear whether the sum includes police crowd control at the Jackson family compound and Forest Lawn cemetery. Los Angeles City Attorney Carmen Trutanich told the City Council that his new management team was going to find out how the city got into the position of providing support for the event and how it could recoup some of the money. His staff also is researching legislation 'so we won't be caught in this lurch again,' he said.
