Locard´s Exchange Principle

In Forensic Science, Locard’s Exchange Principle holds a special place as it unfolds an interesting slant that helped investigators (still helping) to solve a plethora of criminal cases effectively. It says that “the preparator of crime will bring something to the crime scene and will leave something from it.”

The principle says every object that gets in contact with another object, connects with another object and leaves a trace. This is quite similar to that of a criminal leaving traces of their crime. As a crime scene investigator, one should apply this particular principle in order to weed out even the minutest detail, an unlikely object, an obvious clue or the not so obvious ones and the likes.

Trace evidence examinations are based on the Exchange Principle. It states that every time two objects come into contact with each other, there is a specific exchange of information.  Investigators can make use of this information in their quest for finding clue and or solving the entire case altogether.

The forensic department and their employees, as a result, are able to get into the nitty-gritty of the crime scene by abiding by this principle and implementing the right strategies to figure out things effectively. After all, in criminology and such similar stream of study, it is crucial that one must get the hang of the psychological context of the subject matter.

It helps the individual to draw the right references, develop unique ideas and build the right insights into perfecting their paper at the end of the day.

Now that you have got the hang of a brief overview of Lockard’s principle and how it works, you must be eager to know about its key significances. We have heard you. Let’s delve into the topic for further clarity and insights.

Examining the Significance of Lockard’s Exchange Principle in Forensic Science

Lockard’ Exchange principle is undeniably one of the most effective and useful algorithms leveraged by forensic departments in order to weed out minute details to resolve tricky criminal cases. Now that you are eager to know about its significance in today’s world, let’s take a look below for extensive insights.

Provides a base for physical evidence analysis

A crime scene always leaves behind multiple physical evidences but only a few could solve the actual case or the mastermind behind the crime. This is where Lockard’s exchange principle walks in. The primary principle of this theory relates to the fact that a criminal always leaves behind the trace of their crime and every time the object gets in contact with another object, it leaves behind a trace, thus, making the task of evaluating physical evidences all the easier and more effective for the investigators. Having said that, one must implement the right strategies and principles to make the most of this game changing principle.

Determining the “partners in crime” gets twice easier

This is again one critical point to be acknowledged when it comes to examining the significance of Lockard’s exchange principle. It is, at times, assumed, a successful crime takes more than a person to gain prominence and completion. This, as a result, makes it all the more important for the investigators to who all were involved in the crime and what actually happened during the hour of the act. By successfully implementing the key elements and approaches of the Lockard’s Exchange Principle, one can easily figure out the evidences and the people involved during the crime scene.

Collection and preservation of evidences gets easier

This is again one crucial point to be noted when it comes to analyzing the key significance of Lockard’s Exchange principle. It goes without saying, solving a crime scene puzzle will not gain prominence if one fails to collect and preserve the pieces of evidences in the way they are supposed to be done. This is again where the principle of Lockard’s Exchange walks in.

With an accurate implementation of the exchange principle, the investigators get to collect and preserve every piece of evidence in a constructively effective manner.

It helps to link crimes as well

Many a time, forensic investigators end up linking multiple crimes while investing a particular crime scene. The credit goes to Lockard’s Exchange Principle! The right strategic implementation and abiding by the laws of this principle helps investigators to link multiple crimes by using common physical evidence.

For example, DNA tests might suggest that the same person has been involved in multiple crimes. This shall further suggest that the suspect has been involved in a couple of more crimes found to be committed at the same scene.

Once investigators are able to link all the crimes, solving the case naturally gets easier for them down the road.

In Conclusion,

Now, if we consider each of the beneficial aspects and the key significances as mentioned above, it seems that this a one-of-a-kind strategy that has solved some of the biggest crime scene mysteries around the world. After all, the history of crime and criminal minds dates back to centuries and ages.

Criminal try to evolve with each passing year in terms of acquiring new methods to commit a crime and honing great skills in terms of leaving no clues behind. Alas! As long as Lockard’s Exchange principle is embraced and practiced by the forensic investigators, things will always fall in the right place for the crime scene bosses.

Now you know what it takes to elaborate on the Lockard’s Exchange principle in your next assignment.

So, keep referring to more such beneficial aspects associated with this topic, keep learning and growing like a real champ.

Now that you are aware of the bigger picture, with the right insights into the nitty-gritty aspects of Locard’s exchange principle, do not forget to implement the strategy or make good use of the acquired knowledge and understanding.
