Bernie Sanders says he'll ban police using facial recognition software

In an effort to avoid a dystopian sci-fi future where Artificial Intelligence knows pretty much everything about you, and a team of cops led by Tom Cruise run around arresting people for crimes they did not commit because of bad predictive analysis; Bernie Sanders and other Democratic candidates have some proposals on how we can stop it.


Recently Bernie Sanders unveiled a proposal that would outright ban the use of facial recognition for law enforcement purposes. It's part of a bigger proposal for a massive overhaul of the criminal justice system. It also comes on the heels of news and studies that have shown how wrong facial recognition algorithms can be, and the kind of damage these programs can do if deployed for law enforcement purposes.

A Georgetown University study found that the NYPD detectives used some creative methods to manipulate their facial recognition system to try and capture a shoplifter. Creative in this case means that the detective thought that the suspect looked like Woody Harrelson from blurry in-store security footage, and then fed a photo of Woody Harrelson into the facial recognition system. An arrest was eventually made in the case.

Another report from The Verge revealed that New Orleans was using its own facial recognition, and predictive analysis system in conjunction with its city-wide network of police cameras.

But law enforcement isn't the only place where AI can wreak havoc on people's lives study conducted by UC Berkeley found that consumer lending algorithms discriminate against minorities. And the ACLU found that an experiment using Amazon's facial recognition software produced some depressing results.

While Bernie Sanders's proposal seems to go the furthest some of the other Democrats will not be outdone. Elizabeth Warren recently wrote a letter to financial institutions citing the UC Berkeley study.

Julian Castro announced that a part of his plan to turn the data tables around the police and use a database to track police wrongdoing. Corry Booker, along with three other Senators, introduced the Algorithmic Accountability Act, which would require companies to study and fix all the systemic issues that Artificial Intelligence systems have with things like facial recognition.

However, it's also important to remember this isn't just that machines are out to get us, it is first and foremost a people issue.

The systems in question did not invent or build themselves, and the statistical models that they use are completely reliant on human input. The NYPD facial recognition system requires a detective to provide an image if camera footage isn't good enough, and if someone decides that someone looks like a movie star or a composite drawing then that increases the chances that a match could be incorrect without it being the machine's fault.

The systems that financial lending institutions use require analysts and data scientists to identify the variables that determine the predictive outcome. And if the people working on the system make unconsciously biased decisions that profile certain borrowers then the outcome will understandably be one-sided.

Something else to consider is the flow of money to the development of these systems, one study found that by 2020 investments in AI-based platforms will reach $1.25 trillion dollars. With that much at stake it's easy to image that more companies and governments will feel pressured to adopt lest they cause an economic downturn by refusing them.

Maybe we need a ban, and maybe we need to pressure out politicians to continue to be on the lookout for way to limit or stop not just the adoption of poorly built systems, but also to enforce way to make their use more a little bit less prone to human error and bias.

When former Pittsburgh Steelers' center Mike Webster committed suicide in 2002, his death began to raise awareness of the brain damage experienced by NFL football players. A 2017 study found that 99% of deceased NFL players had a degenerative brain disease known as CTE (chronic traumatic encephalopathy). Only one out of 111 former football players had no sign of CTE. It turns out, some of the risks of traumatic brain injury experienced by heavily padded adults playing at a professional level also exist for kids with developing brains playing at a recreational level. The dangers might not be as intense as what the adults go through, but it can have some major life-long consequences.

A new PSA put out by the Concussion Legacy Foundation raises awareness of the dangers of tackle football on developing brains, comparing it to smoking. "Tackle football is like smoking. The younger I start, the longer I am exposed to danger. You wouldn't let me smoke. When should I start tackling?" a child's voice can be heard saying in the PSA as a mother lights up a cigarette for her young son.

On Tuesday morning, President Trump tweeted about some favorable economic numbers, claiming that annual household income is up, unemployment is low, and housing prices are high.

Now, just imagine how much better those numbers would be if the country wasn't mired in an economy-killing trade war with China, bleeding out trillion-dollar-a-year debts, and didn't suffer from chaotic leadership in the Oval Office?

At the end of tweet, came an odd sentence, "Impeach the Pres."

October is domestic violence awareness month and when most people think of domestic violence, they imagine mostly female victims. However, abuse of men happens as well – in both heterosexual and homosexual relationships. But some are taking it upon themselves to change all that.

At this point most reasonable people agree that climate change is a serious problem. And while a lot of good people are working on solutions, and we're all chipping in by using fewer plastic bags, it's also helpful to understand where the leading causes of the issue stem from. The list of 20 leading emitters of carbon dioxide by The Guardian newspaper does just that.

Before the release of "The Joker" there was a glut of stories in the media about the film's potential to incite violence.

The FBI issued a warning, saying the film may inspire violence from a group known as the Clowncels, a subgroup of the involuntarily celibate or Incel community.

Incels an online subculture who believe they are unable to attract a sexual partner. The American nonprofit Southern Poverty Law Center describes them as "part of the online male supremacist ecosystem" that is included in its list of hate groups.
