I'm Shattered : Dexter Is A Fraud.

N.Y. Times Magazine article argues that blood spatter analysis is woo (unless done with mathematical  precision).  Dexter is too young to have been exposed to the technical rigors that blood analysis requires.

But there are historical accounts going back to the 1890s, and you can do online courses these days, picking up skills and theory quite quickly especially if you have access to lab equipment. (Futurelearn.com which I’m a fan of, has a few intro forensic science courses, and I think coursera does too)


Plus, have you seen what they’re using to children learn maths and sciences these days?? oh oh Even zombie apocalypse comes into subject matter!


I found this article on micro fluid dynamics research fun to read. It’s from 2013.

(I read New Scientist weekly, and tend to catch scraps of intriguing reports)


What’s scary is that fire investigation is also apparently turning out to be woo, yet people have been convicted of arson, and even murder, using it. 


Another "science" that has been debunked is bite analysis. That is where the expert can match the criminal to the crime by matching tooth marks on an object or person with the set of the criminal's teeth.


....but, DNA from spittle?? cheese
