What is the difference between a witness and a Crown witness?
Mark was to appear as a Crown witness, having made a detailed confession; in exchange for a suspended sentence.
Mark was a drug dealer and making confession to police after arrested. But I didn't understand the meaning of Crown?
The 'Crown' in English law is the Queen or King, i.e. the state.
All criminal prosecutions in England are undertaken in the name of the Crown - the Queen or King. A Crown witness is therefore a witness for the prosecution.
