The Ancient Babylonians are believed to be the first people to use fingerprints. They would place their prints onto a sheet of papyrus paper to signify who they were when they had finished a business arrangement. The New York State prison system instituted the first modern usage of prints in 1903 to identify criminals who were imprisoned within the state. The Untied States started taking the fingerprints of enlisted men the same year to help them identify soldiers killed in battle. The methods used back then were simple and crude compared to the standards of today as the fingerprinting dallas police officers did back in the early days was transformed by technology.
The old method was to have a person put an ink or dye onto their fingers and then press them against a cardboard sheet. The ink would transfer onto the cardboard creating an image of the ridges at the tip of the fingers. These ridges have identifying patterns that can be attributed to a single person. Thus, when an investigator compared these ridges to other prints taken from a crime scene, they could sometimes ascertain who those prints belonged to that was left behind at the scene.
The process of identification has remained much of the same over the years. An investigator would obtain prints from a crime location and then take them back to the office to see if they matched anything they have on file. They can also obtain prints from a suspect and compare them to what they had previously found. A major problem was prints getting smudged while collecting them at a scene.
Legal experts found that the ways different police departments collected and interpreted data from crime scenes was subjective and could lead to questionable conclusions. The Federal Bureau of Investigation, referred to as the FBI, worked to create standards that would ultimately change that perception when they instituted formal procedures for data collection and storage. They eventually started using computers to do much of the work that had been done by hand.
The FBI also started to incorporate new procedures in how prints were taken of fingers. This resulted in the searchable data base people see so often on crime based television shows. The idea of using images of finger tips to track down and arrest criminals became common place and has been in use for a few decades now.
Eventually the ways fingerprints were obtained at crime sites changed. Police departments starting using X ray technology to capture an image. This method can be used on wood and leather. Materials like these tended to absorb the print enough that older technologies were not useful in capturing the images.
The X ray equipment is making traditional methods obsolete. The pictures the equipment takes is much clearer than before. Using vapors and powders to make traces is fading away.
Crime fighting techniques are constantly evolving through greater use of current technologies. The police have been able to figure out who committed a crime through better collection and analysis efforts. The history of fingerprinting dallas police officers have used show how new technologies have affected this field and made the police more efficient at targeting the right suspects to arrest for wrongful behavior.
