Question and answer
Discuss the fundamental principles behind the uniqueness of fingerprints.
A fingerprint will remain unchanged during an individual's lifetime The ridges on the grasping surfaces of hands and on the soles of feet are present at birth and remain unchanged for life except for size as growth occurs. [ They may be obscured by deep tissue damage that causes scarring, like burns for example. However these scars may also be useful as points of identification. 3. Fingerprints have general ridge patterns that permit them to be systematically classified Sir Francis Galton in his book Finger Prints (1892) classified fingerprint patterns into three main kinds; Arches; 5 %
population Loops; 60 - 65 % Whorls; 30 - 35 % This classification was extended by Sir Edward Henry in 1897 and it was this modified system that was adopted by Scotland Yard in 1901. This system of classification, with some variation, is still in use today in English speaking countries. Classifying the general pattern of fingerprints allows them to be stored in a filing system and subsequently retrieved for comparison. Modern technology has allowed this process to transferred to computers with the advent of automated fingerprint identification systems (AFIS). ]

How important is effective communication between County Commissioners and criminal justice agencies?
Weegy: Communication consists of the following according to Merriam Webster, “: a process by which information is exchanged between individuals through a common system of symbols, signs, or behavior.” (Communication, 2009) Within the idea of communication, [ there exist two main types for humans, verbal and non-verbal communication. Each of these main types has subsets or components, which allow us to break the idea of communication down and study it more. Within verbal communication, the following applies, “Researchers are unable to reach a consensus on the exact number of styles; however, most are willing to concede that they cluster around four dimensions: blaming, directing, persuading, and problem solving.” (Grubb, Hemby, 2003) Within non-verbal communication, you have writing or communication through the written word, and you have body language. “Criminal justice professionals must be able to write clearly and coherently. Excerpts from reports are often introduced into court proceedings, and superiors review them as part of the investigative process.” (Grubb, Hemby, 2003) ] (More)
