In LA, you have about 60% chance of getting away with murder.

""How many 2007 homicides were solved?

An arrest was made in about 41% of all murders committed in Los Angeles County in 2007, according to data collected by the Homicide Report.

The total rises to about 46% when only cases from the first six months of 2007 are considered; presumably, some homicides from the second half of the year may need only weeks or months of further investigation to be resolved.

The HR analysis shows that there was virtually no difference in success rates overall in 2007 between the Los Angeles Police Department and the Los Angeles County Sheriff’s Department.

Although these two agencies--both among the largest in the country--follow very different models in investigating homicides, both agencies had arrested suspects in about 40% of all homicide cases by year’s end. The finding suggests that the problems involved in catching and jailing killers may be bigger than the police. Community attitudes and behaviors and prosecutors’ thresholds for filing homicide charges may have more to do with whether murderers end up behind bars than any particular law-enforcement model.""
