1. Forensic Science Wasn’t Invented by Scientists
Although its methods are highly scientific, forensic science owes its beginnings to cops who relied heavily on observation and common sense.
2. Fingerprints Aren’t Foolproof
Real-life forensic scientists will tell you, however, that while each person does have unique fingerprints, matching them can be difficult, even for experts.
3. Bullets Aren’t Foolproof Either
While this ballistics theory is sound, the process of actually finding a match for the gun and bullet has no strong statistical formula behind it.
4. DNA Testing Saves Lives
To date, DNA testing has exonerated more than 242 wrongfully-convicted individuals.
5. DNA Testing Makes Mistakes
Unfortunately, the reverse can also happen. DNA testing has never been 100% accurate. There have been more than 50 false incriminations based on faulty
6. Teeth Are Trustworthy
What piece of crime scene data is responsible for identifying over 93% of remains? Dental records. Because bones are among the sturdiest parts of the body, they are often the best-preserved area in remains.
7. Bugs Are Good For You
Insects have proven to be a reliable indicator of an individual’s time of death. There is an entire field of forensic science dedicated to the study of insects in the crime scene – forensic entomology.
8. The Nose Knows
Dead bodies emit certain smells when they die, often to the revulsion of many. These pungent aromas are actually a combination of chemical gases emitted by the corpse, like ammonia and sulphur. Scientists are currently working on machines that will be able to detect these chemical gases, thereby determining where a corpse may be found.
9. Deleted Computer Files Aren’t Always Gone
Savvy forensic scientists may be able to find evidence that’s been deleted from a computer. Every time you “delete” a file from a computer, the file is simply set aside, hidden, and marked as data waiting to be rewritten.
10. Forensic Science Comes Second
Despite its reputation, forensic science, is only the second best method of identifying criminals. What’s number one? Eyewitness account, of course. Eyewitness testimony far outweighs the deductions based on forensic scientific methods.
