Alhambra police say crime prevention technology is working

The Alhambra Police Department says crime has dropped in the city since the agency started using the crime tracking and prevention system Predictive Policing, World Journal (世界日报) reports. Predictive Policing, or "PredPol," identifies areas where crime could possibly occur next based on data from the previous five years. Alhambra is the first city in Los Angeles County to use PredPol city-wide.

The total number of reported crimes in Alhambra has indeed decreased since Alhambra police began using PredPol in May, according to crime data from the Alhambra Police Department, and in July reached the lowest point since November 2012. Hit-and-run and automobile burglary reports in particular have been decreasing since May. But vandalism, grand theft, and robbery have continued to fluctuate and rise. 

Crime data from November 2012 to July 2013

Alhambra Vice Mayor Stephen Sham and Police Chief Mark Yokoyama introduced the new technology to the Chinese press at a press conference on Aug. 12. Sham encouraged San Gabriel Valley residents to report crime and increase PredPol's reliability with more accurate data. Alhambra invested $15,000 on the system this year, according to Yokoyama.
