Uncommon facts about fingerprinting

There are important things you should know about the fingerprints. Probably you know that criminals burn fingerprints to avoid being identified. Or you have heard that every person has a unique pattern. However, in this post, we share useful facts about fingerprints that are not known by most people.

What you should know about fingerprints

Fingerprinting is not foolproof

It is quite comforting to believe that criminal investigators can find the bad guy in case he forgets putting on gloves before committing a crime. You should note that this particular method of identification is not foolproof. In fact, there are no minimum comparison points. Also, human beings are fallible.

Removing fingerprints is not an easy task as it may appear. In the last few decades, fingerprinting was quite common that criminals had to avoid being identified through them. Thus, they had to burn them off using an acid or even cutting them off.…
