To understand the main drivers of incarceration, the public needs to see how many people are incarcerated for different offense types. But the reported offense data oversimplifies how people interact with the criminal justice system in two important ways: it reports only one offense category per person, and it reflects the outcome of the legal process, obscuring important details of actual events.
First, when a person is in prison for multiple offenses, only the most serious offense is reported. So, for example, there are people in prison for violent offenses who were also convicted of drug offenses, but they are included only in the “violent” category in the data. This makes it hard to grasp the complexity of criminal events, such as the role drugs may have played in violent or property offenses. We must also consider that almost all convictions are the result of plea bargains, where
defendants plead guilty to a lesser offense, possibly in a different category, or one that they did not actually commit.
Secondly, many of these categories group together people convicted of a
wide range of offenses. For violent offenses especially, these labels can distort perceptions of individual “violent offenders” and exaggerate the scale of dangerous violent crime. For example, “murder” is an extremely serious offense, but that category groups together the small number of serial killers with people who committed acts that are unlikely, for reasons of circumstance or
advanced age, to ever happen again. It also includes offenses that the average person may not consider to be murder at all. In particular, the felony murder rule says that if someone dies during the commission of a felony, everyone involved can be as guilty of murder as the person who pulled the trigger. Acting as lookout during a break-in where someone was accidentally killed is indeed a serious offense, but many may be surprised that this can be considered murder in the U.S.
