FRESNO, Calif. — While officers raced to a recent 911 call about a man threatening his ex-girlfriend, a police operator in headquarters consulted software that scored the suspect’s potential for violence the way a bank might run a credit report.
The program scoured billions of data points, including arrest reports, property records, commercial databases, deep Web searches and the man’s social- media postings. It calculated his threat level as the highest of three color-coded scores: a bright red warning.
The man had a firearm conviction and gang associations, so out of caution police called a negotiator. The suspect surrendered, and police said the intelligence helped them make the right call — it turned out he had a gun.
As a national debate has played out over mass surveillance by the National Security Agency, a new generation of technology such as the Beware software being used in Fresno has given local law enforcement officers unprecedented power to peer into the lives of citizens.
