One out of every five people arrested is on parole or probation — a lower number than law enforcement expected — according to a newly published study.
Researchers examined to what extent people on parole or probation contribute to crime (as measured by arrests).
They used data from Los Angeles, Redlands, Sacramento and San Francisco police over more than three years, ending in June 2011.
The Council of State Governments Justice Center, a nonpartisan and nonprofit organization based in Kentucky, found:
- The majority of adult felony and misdemeanor arrests (77%) involved people who were not under supervision.
- When looking only at drug violations, one out of every three people arrested was on probation or parole.
- Total arrests fell by 18 percent. Meanwhile, the number parolees arrested fell 61 percent, and people on probation declined 26 percent.
The data shows there’s a “small fraction” of parolees who are “contributing disproportionately to drug-related crime,” Redlands Police Chief Mark Garcia said this week in a news statement about the study.
As a whole, though, Sacramento Police Chief Rick Braziel said:
“Our assumption has been that people under probation and parole were driving our arrest activity, but the data suggests otherwise,” he said.
“This new information opens up opportunities for law enforcement agencies, which are grappling with huge budget cuts, to work with partners in probation and parole to be more efficient and targeted in our prevention, intervention, and enforcement efforts.”
The study was paid for by the Public Safety Performance Project of the Pew Center on the States, the Public Welfare Foundation, the Fund for Nonviolence and the Rosenberg Foundation.
