The District experienced a rise in crime in 2007, leading Police Chief Cathy Lanier to express disappointment Monday while vowing that changes she is now implementing will eventually reverse those trends.

Lanier, who took over as head of the Metropolitan Police Department in January 2006, told the D.C. Council’s public safety committee that crime increased by 4 percent overall last year. Violent crime was up 1 percent and property crime 5 percent.
