You probably didn't know that you had a threat rating, but you probably do. It's just like a credit score, but instead of determining whether you get a car loan, it may determine whether the cops will shoot you or not.

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.

That sounds very useful. If the cops are heading into a dangerous situation, they should know that. Fresno’s Real Time Crime Center is just one facility that does these instant background checks. New York, Houston and Seattle also have them.
However, there is one little problem with this system.

As officers respond to calls, Beware automatically runs the address. The searches return the names of residents and scans them against a range of publicly available data to generate a color-coded threat level for each person or address: green, yellow or red.
Exactly how Beware calculates threat scores is something that its maker, Intrado, considers a trade secret, so it is unclear how much weight is given to a misdemeanor, felony or threatening comment on Facebook....
Navarro said the fact that only Intrado — not the police or the public — knows how Beware tallies its scores is disconcerting. He also worries that the system might mistakenly increase someone’s threat level by misinterpreting innocuous activity on social media, like criticizing the police, and trigger a heavier response by officers.

How this software arrives at these score makes all the difference. I would also include the problem of maybe the person in question doesn't live at that address anymore.
Now some might point out that this could save lives, not just of police officers, but the public as well. This point is correct. More information could indeed save lives, but only if it is the correct information.

For instance, we already have a few systems of threat assessments in this country, the most notable is the No-Fly list. Both the No-Fly List and Beware software are without any public oversight whatsoever.

There are 64,000 people on the No-Fly List, most of which are still allowed to buy guns. The No-Fly List was 18,000 names long when President Obama took over.
The No-Fly List has kept us safe from this 18-month old girl.

There are several ways to get on the No-Fly List, including having similar names as terrorists, "refusing to spy for the FBI", clerical errors, open warrants, and controversial tweets.

The government guidelines published by the Intercept barred agencies from blacklisting people based on information that is “unreliable or not credible.” But it does point out that social media posts “should not automatically be discounted” when deciding whether someone belongs on a blacklist.

Political activity can also get you on the No-Fly List.

Professor Walter F Murphy is emeritus of Princeton University; he is one of the foremost constitutional scholars in the nation and author of the classic Constitutional Democracy. Murphy is also a decorated former marine, and he is not even especially politically liberal. But on March 1 this year, he was denied a boarding pass at Newark, "because I was on the Terrorist Watch list".
"Have you been in any peace marches? We ban a lot of people from flying because of that," asked the airline employee.
"I explained," said Murphy, "that I had not so marched but had, in September 2006, given a lecture at Princeton, televised and put on the web, highly critical of George Bush for his many violations of the constitution."
"That'll do it," the man said.

This is the kind of accuracy performance we should probably expect from these Real Time Crime Centers.

For the first several years, credit scores were used as part of creating the No-Fly List.
If that sounds weird to you consider China.

I'm most worried about China's planned Social Credit System, which the New Republic described as "fiercely ambitious, authoritarian, technologically sophisticated, and likely to disrupt the lives of millions of people." What makes China's SCS so insidiously terrifying is that it goes well beyond Western-style credit scores to create a mandatory scheme to "rate the trustworthiness of citizens in all facets of life, from business deals to social behavior."
According to the BBC, "By 2020, everyone in China will be enrolled in a vast national database that compiles fiscal and government information, including minor traffic violations, and distills it into a single number ranking each citizen."
Eventually, these scores will be used to determine eligibility for everything from employment and credit to various social benefits. In practice, private company tests of the system are already using similar scores on dating sites, and acknowledging that even legal activities like playing too many video games all day or buying socially unacceptable products could incur penalties.
The SCS is also intended to encourage informing on your neighbors. The system's planning document states that the "new system will reward those who report acts of breach of trust."

All I am saying is, "What could possibly go wrong?"
