Updated: 01/04/2007 - Wisconsin has a new top cop. Republican J.B. Van Hollen took the oath of office Wednesday at the capitol. As Attorney General, Van Hollen heads up the state Justice Department--which oversees the state crime lab. As we've reported, DNA evidence is piling up at the lab, creating a backlog in the system. Van Hollen says that's not acceptable, but admits there's no quick fix.
