when were fingerprints first used in crime detection
Fingerprint Although ancient peoples probably did not realize that fingerprints could uniquely identify individuals,[61] references from the age of the Babylonian king Hammurabi (reigned 1792-1750 BCE) indicate that law officials would take the fingerprints of people who had been arrested.[62] During China's Qin Dynasty, records have shown that officials took hand prints, foot prints as well as finger prints as evidence from a crime scene.[63] In China, around 300 CE, handprints were used as evidence in a trial for theft. By 650, the Chinese historian Kia Kung-Yen remarked that fingerprints could be used as a means of authentication.[64] In his Jami al-Tawarikh (Universal History), the Persian physician Rashid-al-Din Hamadani (also known as "Rashideddin", 1247â€“1318) refers to the Chinese practice of identifying people via their fingerprints, commenting: "Experience shows that no two individuals have fingers exactly alike."[65] In Persia at this time, government documents may have been authenticated with thumbprints.[citation needed]
Background check There are a variety of types of investigative searches that can be used by potential employers. Many commercial sites will offer specific searches to employers for a fee. Services like these will actually perform the checks, supply the company with adverse action letters, and ensure compliance throughout the process. It is important to be selective about which pre-employment screening agency one uses. A legitimate company will be happy to explain the process. Many employers choose to search the most common records such as criminal records, driving records, and education verification. Other searches such as sex offender registry, credential verification, skills assessment, reference checks, credit reports and Patriot Act searches are becoming increasingly common. Employers should consider the position in question when determining which types of searches to include, and should always use the same searches for every applicant being considered for one.
