Texas residents may be interested in learning about an unproven mind-reading tool that cops around the world are using. The tool is called Scientific Content Analysis, or SCAN. The creators of this tool claim that it can identify deception. The FBI, CIA and law enforcement in local agencies have been using this method for decades despite the fact that there is no reliable science behind it.

The creators of this product say that sifting truth from deception is an easy process and involves just three simple steps. The first is giving a suspect a pen and paper. Next, the suspect is asked to write down their version of what happened regarding a crime. Third, law enforcement will analyze the statement and then supposedly be able to solve the case. The goal with this tool is to reduce time-consuming and costly outside investigation and help clear innocent individuals.

This tool is akin to other investigative tools that have received a lot of scrutiny, like the photo analysis and bloodstain pattern analysis. These techniques may be able to guide an investigator or shore up a case, but they usually do not hold up in court because they have little to no scientific backing. A study conducted in 2016 that was performed by four scholars showed that there was “no empirical support” of SCAN, which means there is no dependable research that shows it actually works.

When an individual is accused of a crime, they may wish to discuss their case with a criminal defense attorney. Criminal defense and drunk driving attorneys are not only for guilty individuals. An attorney may speak with law enforcement and eyewitnesses and examine CCTV footage and other evidence to help prove a person’s innocence or show reasonable doubt. The attorney may even represent a client in court.
