RAP SHEETS IN CRIMINOLOGICAL RESEARCH - CONSIDERATIONS AND CAVEATS

The types of errors found in official criminal history records are not completely understood by many researchers, and this lack of understan ding can lead to serious misinterpretations. Analyses of a recently de veloped database of New Orleans offenders indicate that the use of rap sheets with a limited catchment area can lead to gross distortions of the effects of variables related to geographic mobility, such as race and age. Evidence from a number of sources indicates that false-negat ive error is a serious problem, particularly in fingerprint-based reco rd systems. In addition, arrest records lend themselves to a variety o f common misinterpretations by researchers in the coding process, incl uding failing to identify multievent arrests, misclassifying arrests, and treating arrest or custody process events as crimes indicating cri minal activity of the individual while free. Solutions to some of thes e problems are suggested.
