The Los Angeles Police Department pioneered the controversial use of data to pinpoint crime hot spots and track violent offenders.
Complex algorithms and vast databases were supposed to revolutionize crime fighting, making policing more efficient as number-crunching computers helped to position scarce resources.
But critics long complained about inherent bias in the data — gathered by officers — that underpinned the tools.
They claimed a partial victory when LAPD Chief Michel Moore announced he would end one highly touted program intended to identify and monitor violent criminals. On Tuesday, the department’s civilian oversight panel raised questions about whether another program, aimed at reducing property crime, also disproportionately targets black and Latino communities.
