Is it OK for social scientists to use statistics in a misleading way when they write for the general public?
Peter Moskos is a professor at John Jay College of Criminal Justice. His Cop in the Hood is based partly on his work as a police officer in Baltimore. Here’s the lede from a piece he wrote in the Washington Post with Neill Franklin, also a former Baltimore cop.
They follow this with:
In many ways, Dante Arthur was lucky. He lived. Nationwide, a police officer dies on duty nearly every other day. [emphasis added]Let’s see – 365 days a year. That makes nearly 180 such deaths each year.
I’ve been out of the crim biz for a while, but that number sounded high to me. So I went to the UCR. Sure enough, in 2007, 140 police officers died in the line of duty. As Moskos and Franklin say, nearly one every other day.
But 83 of those officers died in accidents, only 57 were homicide victims – one every 6 days. Still a lot. But how many of those were drug-related? The UCR has the answer:
One.
Nor was 2007 unusual. In the decade ending 2007, 1300 police officers died on the job. About 550 of these were in felonies, not accidents. And of these, 27 were drug-related. Three a year is still too many, but it’s a far cry from one every other day.
Maybe I should have looked at a DVD of The Wire instead of the UCR.
Officer Arthur will not appear in this table of the UCR. It counts only deaths. So I looked at data on assaults on police officers. There were 59,000 non-fatal assaults on police officers, nearly a third of them in “disturbances,” i.e., fights (at home, in bars, etc.). Curiously, the UCR does not have a separate category for drugs in these tables. In the Arrest category, it has Robbery, Burglary, and Other, which must include drugs. In that Other category, 174 assaults were with guns.
Total Assaults | 59,201 |
Disturbance | 18,789 |
Other Arrest | 8,935 |
Firearm | 174 |
Using the drugs/other ratio from the table on deaths (about 1/3), we get about 60 non-fatal shootings (like that of Officer Arthur) in 2007 – one tenth of one percent of all assaults on police officers.
Moskos and Franklin argue that federal laws should allow states to make the manufacture and distribution of drugs legal and regulated rather than criminal. The authors make several good arguments against current drug laws, which have created many problems that legalization might ameliorate. But I’m skeptical as to whether legalization would make much of a difference in police safety.
