New Technology in Modern Law Enforcement
In today’s society crime has followed the path of technology. As technology has grown and expanded so has the ways that criminals commit their crimes. They are not the only ones that have started to use this new technology. Law enforcement has also developed new ways to keep records of criminals. Fingerprint records and DNA records are just a couple of ways that have helped law enforcement. Both types of records have many similarities but they also have many differences.
Both Fingerprints and DNA are unique to a person. There are databases for both in which law enforcement can search for a match to evidence. Both have certain componets that are unique to each. Fingerprints all have ridges that can be used to identify a person. DNA has certain chromosomes that are unique to each DNA sample used to identify a person. They are both excellent ways to append a criminal. Most criminals leave either a fingerprint or DNA at the scene of a crime. When collected properly they can help law enforcement solve crimes otherwise thought unsolvable.
There are many differences in both processes. Fingerprints are physical evidence. DNA is biochemical evidence. Fingerprints are pulled off of evidence found at crime scenes. They are then run thru the Integrated Automated Fingerprint Identification System, or IAFIS, which is a national fingerprint and criminal history system. (Integrated Automated). DNA if found is taken to a lab where it goes thru chemical processes to extract the 13 Str’s, Short Tandem Repeats, and another which identifies the sex of the person. (How DNA).
Even though they have many similarities and differences the advances in modern technology have made these processes just a couple of the ways law enforcement can catch and prosecute criminals. With the way technology is heading hopefully one day criminals will not be able to get away...
