Select and research ONE case from the list below, and then proceed to write an essay in the form of a case study, which incorporates all of the points listed below:

• R v Angela Cannings [2004] EWCA (Crim) 01.

( you can choose which one as I'm not mind)

• An explanation of the point during the Criminal Justice System that the miscarriage of justice occurred;
• A brief analysis of the evidence presented in court;
• The verdict;
• The sentence;
