Criminal Justice Paper on Evolving Technology

Evolving Technology

Technology has changed for the better. For a police officer in charge of burglary investigation needs technology to gather evidence. There are different technologies for investigating drops of blood, a hammer, shoeprints and handprint evidence. For bloodstains, the police officer may use Blood Stain Pattern Analysis (BPA) whereby the blood is run through a database to check for the matches. This helps identify the real perpetrator of the crime (Bevel & Gardner, 2008). Additionally, the police officer can collect the blood, swab it on a cotton wool swab and smear it on a slide under a microscope. This technology enables the police officer to conduct a thorough investigation by looking for the blood matches to get the right person for arrest.

For a hammer, forensic science is used to check for the victim’s blood or skin cells and develop a DNA profile. This technology enables the police or investigators check for the identity of the suspect in their database by matching the collected DNA profile and the fingerprints. When someone leaves shoeprint and handprints, the first prints should be marked off for the investigator. Electrostatic dust lifter technique is used to recover visible and invisible footwear evidence in the crime scene. This technology helps police know the type, make, approximate size, events that occurred, and the number of suspects involved in the crime.

A prison guard can use Concealed Weapon and Contraband Imaging Detection Systems (CWCIDS), ion mobility spectrometer (IMS) scanning for checking drugs and backscatter X-Ray that detect both metallic and non-metallic contraband (Byrne  & Rebovich,  2007). Additionally, biometric monitoring system and a Millimeter Wave Portal technology are used to identify hidden objects. These technologies enable the prison guard to screen people and detect any contraband easily at the prison entrance.

The technology available for probation officers is the global positioning system (GPS), a database shared between the law enforcement, and correction institution. GPS is a tracking device attached to the person to monitor his movement. This system enables the probation officers to know and monitor the location of a probationer.

In the case of Kyllo v. United States, 533 U.S 27 (2001), there is the usage of thermal imaging technology to identify heat reading that would indicate the heat lamps that have been utilized  for the growth of marijuana. The use of this technology towards Kyllo by the law enforcement violated Kyllo’s fourth amendment right. The Supreme Court ruled out that the government used a device that violated the rights of Kyllo.

In my opinion, I chose police officer career as the most advancing in new technology. I would like to learn about the bloodstain pattern analysis technology and blood swab. These new technologies would help me to advance in my investigation career. Moreover, with this technology, police officer, and courts are able to arrest and prosecute the exact people who committed crimes.
