The study and practice of Criminology has taken on a whole new life. Much of that can be attributed to public awareness of the field generated by current TV shows. As science continues its march, science and criminology have become one. DNA is one area that has exploded on the scene and opened many career opportunities for students with active intuitive minds. There are many areas where the science of criminology plays an important role.
With the potential for growth, colleges are beginning to offer more specific programs in criminology. Online degree criminology courses are being offered, as those institutions were quick to recognize the trend and are offering some of the best and most varied programs in the field. It is an expansive subject that can lead to many interesting and challenging directions and make a difference in the lives of millions.
Criminologists have found a link between certain crime and behavioral issues in domestic violence crimes. Research shows that by studying those cases, criminologists can advance the training, education and understanding among criminologists and domestic violence victims. By studying the psychology of emotional appeals used by violent men, women can actually learn how to protect themselves from abusive partners by allowing the justice system to try and punish the attacker, rather than give in to their emotions. Also, by studying methods that attackers use to manipulate victim, criminologists can identify the people who are apt to threaten more future victims.
One of the biggest advancements in the field since fingerprinting is DNA testing. DNA is playing an important role in criminal cases in Colorado and has since become part of routine criminology. It has been proven to be reliable source of information, but as its use becomes widespread, many questions are being asked about the legality of certain specific uses of DNA, particularly the requirement for DNA samples from convicted offenders. Of even more concern are the samples taken from prisoners who have been arrested but not convicted. The question of whether taking swabs from an un-convicted person violates his constitutional rights. Proponents argue that the practice is no different than fingerprinting, but with many more useful purposes.
Criminologists believe that ongoing collection of DNA will result in the removal of more criminals off the streets of our cities. Interestingly, they also believe that fewer guilty people will be wrongly convicted. Taking it one step further, persons convicted erroneously of murder who are awaiting the death penalty can be exonerated.
The difference with DNA is that it can be done more conclusively and with less room for error, resulting in more guilty people being convicted of their crimes, and more innocent people being freed of their wrongful charges.
With a solid base of DNA samples, criminals can be removed from society quicker and at less expense than traditional ways. One example is serial murderers or rapists who in many cases would have had a DNA sample on file for other offenses they committed. With that information, they would have been arrested and put away much before any other murders or rapes were committed.
