how computers are essential in criminal justice field

Computers take part in a big role in the Criminal Justice Field. So far computers have allowed us to make it accessible for witnesses to go through and look for a suspect's picture on the screen. Computers have enabled us to be able to do DNA testing. Which now only takes the labs a short time to process, and finding criminals from cases 15+ years ago can now be charged for their actions. There are laptop computers in police vehicles; therefore, police officers can look up information right then and there instead of having to wait until they get back to the station. Some cars even have the wireless Internet connection that goes through satellite which allows them to do even greater things. Computers have also allowed the use of fingerprinting to expand. Agencies can now take someone’s fingerprints and send them through the computer and find out if they are linked to any other cases going on at the time, or any other cases in the past. A computer forensic scientist or technician is still considered a cutting edge profession in the criminal justice field. With the increase of cybercrime, cyberterrorism, identity theft, and Internet child predators, computer forensic scientists are needed to track seemingly traceless criminals. Computer forensic scientists work with law enforcement officials, legal teams, independent companies and the government to conduct investigations, retrieve evidence and sometimes even testify in court. Computer forensic scientists are in high demand because they need to have a very thorough, practical knowledge of computers, networks, hacking, data retrieval, information security, and computer surveillance, as well as criminal justice concepts like confidentiality, privacy laws, evidence handling and more. Generally, computer forensic scientists are supervised during their work by a forensic scientist, and they must have the ability to work well in stressful situations. Depending on the casework, these professionals may also encounter irregular schedules and long overtime hours. The Bureau of Labor Statistics predicts that the job outlook for computer forensic investigators will be excellent for the next several years. This prediction is for self-employed investigators as well as those employed by a firm. Investigators who work on their own will enjoy more flexibility, but may make far less or far more than they would in a firm. Salary for self-employed investigators varies on their geographic location, experience and number of clients. Firms offer more stability and usually provide benefits like paid vacation and health insurance. The average salary reported in 2006 by the Bureau of Labor Statistics was $33,750 for private investigators, although those in the computer forensics field generally earn higher salaries. The median range for private investigators settled between $24,180 and $47,740. Computer forensic scientists and investigators are expected to be highly educated professionals, so a bachelor’s degree is required. A Master’s degree in a field like computer science of criminal justice can be extremely beneficial to acquiring the top level jobs, as students in these programs will learn about all the cutting edge technologies, systems and concepts needed to succeed in computer forensics. A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem.Conventionally a computer consists of some form of memory for data storage, at least one element that carries out arithmetic and logic operations, and a sequencing and control element that can change the order of operations based on the information that is stored. Peripheral devices allow information to be entered from external source, and allow the results of operations to be sent out.A...
