pretend science and the power of the government

The power of government matched with the authority of unethical experts can do unimaginable damage.

The Motherisk Drug Testing Lab at the Hospital for Sick Children in Toronto was used for over twenty years to do hair analysis on people suspected of illegal drug use.
For more than two decades, Motherisk performed flawed drug and alcohol testing on thousands of vulnerable families across Canada, influencing decisions in child protection cases that separated parents from their children and sometimes children from their siblings. 
Decades.
Child welfare agencies in five provinces across Canada had paid for Motherisk's hair-strand tests, believing they were scientific proof of substance abuse. The tests were often used in custody and child protection cases in part to decide whether a parent was fit to care for a child.

Motherisk scientists were operating without any forensic training or oversight. Its test results, it has now been discovered, were faulty opinions. 
The science had seemed straightforward. Simple strands of hair are a warehouse of information, storing biomarkers that can reveal proof of drug and alcohol use. They hold that information longer than blood or urine.
This is similar to polygraph exams. Someone believes they are scientific but they are actually only faulty opinions.

Like the unscientific hair strand tests--and ballistics and bite-mark and all kinds of forensic tests--the polygraph is used to deprive people of their freedom and to break up families.

Over two years ago, Conor Friedersdorf wrote in The Atlantic about the practice of using unscientific tests and the tragic miscarriage of justice that often results. Friedersdorf writes:
...as the Washington Post made clear Saturday in an article that begins with a punch to the gut: "Nearly every examiner in an elite FBI forensic unit gave flawed testimony in almost all trials in which they offered evidence against criminal defendants over more than a two-decade period before 2000," the newspaper reported, adding that "the cases include those of 32 defendants sentenced to death." 
The article notes that the admissions from the FBI and Department of Justice "confirm long-suspected problems with subjective, pattern-based forensic techniques—like hair and bite-mark comparisons—that have contributed to wrongful convictions in more than one-quarter of 329 DNA-exoneration cases since 1989."
When you hear prosecutors talk about forensic proof of guilt, keep your skepticism handy. Those forensic tests, pretend science, will be used against you and it will be used to damage your family.

Junk science paired with the force of government should frighten us all.
