you shouldn't only look for case studies, you should have LCMD
LEGISLATION, CASES, MEDIA REPORTS AND DOCUMENTS
textbooks for cases
newspapers covers the Media reports part in LCMD
the news covers Media reports also
the internet you can find case studies
I have set up some LCMD threads- check out the forums
heres the link for the crime LCMD
theres some there to get you started
remember to refer to LCMDs because it is stated in the syllabus and rubric that you must refer to them to achieve a top band in your essays
good luck
