Forensic scientist uses science, expertise, and technology to analyze the evidence to reconstruct a crime scene and provide information about the offenders. Forensic scientists examine the evidence at crime scenes alongside detectives to construct likely models that aid in prosecuting offenders.
In addition to working in a lab and on-site at crime scenes, forensic scientists frequently testify in court about their results.
Although forensic science in the real world differs significantly from that in fictitious television dramas, it is just as fascinating. Here are some facts about forensic science in the real world that you probably didn’t know:
Scientists did not create forensic science.
Even though it uses highly scientific procedures, forensic science has its roots in police work, which mainly relied on observation and common sense. The development of forensic science as we know it today began with police officers using fingerprints to identify criminals.
The most remarkable developments, including DNA testing and UV light screening, appeared much later and required more sophisticated technology.
Everything you do online is monitored.
One of the simplest ways of monitoring is internet tracking. Everyone, even the government, has access to the Internet, which is a huge public space. The government could monitor anyone’s online activities if they so desired, just as they are doing with many people right now. A skilled computer technician can track every website you visit, every mouse click, and every keystroke you make. Because of this, the government has employed a number of these people to keep an eye on residents in an area code, particularly those who may be involved in criminal behavior.
Fingerprints Aren’t Always Accurate
On tv shows and movies, it usually just takes a matter of time before the perpetrator is apprehended once a fingerprint is found at the crime scene. The most devastating artifact that might be used against a person appears to be a fingerprint. However, while each person has a distinct fingerprint, even experienced forensic scientists will admit that matching them can be challenging.
Even though each person’s fingerprints are unique, one‘s patterns are so complex and diverse that it requires a skilled eye to spot a match. Although computer technology has greatly facilitated this procedure, forensic specialists with extensive experience caution that there is no statistical method for matching fingerprints that are 100 percent error-free.
Teeth are reliable.
What crime scene information allowed for the identification of almost 94% of the remains? One’s dental history. Bone is among the body’s strongest tissues, making it frequently the best-preserved component in fossil remains for forensics test. This makes for a fairly trustworthy means of identification when paired with the reality that each person has a distinct dental imprint.
Computer Files Aren’t Always Permanently Removed.
The evidence that has been removed from a computer might still be recoverable by astute forensic experts. When you “delete” an item from a computer, it actually just gets hidden, pushed aside, & marked as data that needs to be written over. Computer analysts take advantage of this phenomenon by creating tools that can find these hidden files and transfer and retrieve the data.
There Isn’t a Perfect Piece of Proof
Contrary to what you may have seen on television, much of the evidence recovered from crime scenes are typically tainted and occasionally rendered useless. The crime scene will already be disturbed by a number of uncontrollable factors, such as the weather and bystanders, even by the time the authorities arrive. Depending on how quickly the investigative team responded, the information might have moved, changed, or even been destroyed.
