Criminal justice bachelor's programs include courses that address ethical issues, police and society, correction and society, and crime control policy. Most courses provide general education in criminal justice, preparing students for work in a number of positions, including police, courts and correctional facilities. In addition, some criminal justice programs specialize in law enforcement for prospective police officers and federal agents and include courses like police report writing, firearms and precision driving.

Crime scene investigators, or CSIs, and scientists in laboratories of law enforcement agencies must hold a bachelor's or master's degree in forensic science, a term that applies to a broad range of sciences applied to analyze evidence. Forensic science professionals are only involved in obtaining information from evidence, so this degree is not a passport to all kinds of law enforcement positions, but it is a requirement if you want to be a CSI.
