There is a lot of difference between the expression ‘linkman’, as one word, and ‘link man’, as two words — a ‘linkman’, as one word, is a person who collects information from several sources and pass on/broadcast it on to others or on a TV news channel, and the expression ‘link man’, as two words, means ‘linking’ or ‘connecting’ a man to a crime or activity, especially in a criminal case where there is evidence to show connection between a person and the crime.
It is suspected that there are several linkmen in Al-Qaeda and other Islamic militant organisations, who do not involve in criminal activities personally/directly but act as a go-between for several groups within the organisation or different organisations.
Note 2: ‘Linkman’, always with a capital ‘L’, is often found in the names of people, e.g. Alfred Linkman, Henry Linkman, Susan Linkman, etc. For an article that explains the origin of this word as a surname, please click here.
