reporter: emelie lagervall used to be a policewoman. e loved being a patrol officer in the swedish municipality of norrkoping. it was her dream job. but one day she gave up and quit. emelie: i became a police officer to prevent crimes. but the way things developed, the number of reports filed just kept on increasing. we were too preoccupied with all the emergencies to deal with preventive work. reporter: now she works for the city council. the work hours are more family friendly. but most importantly, there's enough personnel to handle the workload, which wasn't the case in the police force. emelie: we had to investigate year-old cases. we'd call people up and say, "hi, we're looking into this now." and they'd reply, "what have you been doing 'til now?" witnesses would say, "back then i might have been able to remember, but a whole year's gone by and i don't even remember what the suspect was wearing. i wasn't taking notes." reporter: she says there are simply too few officers, though more have been hired in recent years. sweden currentl
