The number of Crown Prosecution Lawyers in the UK is approx one fifth of the number of Barristers and one twentieth the number of practising lawyers - they therefore have a high case load and less time than shown in the series to focus on individual cases, accepting of course that high profile ShowTrials would merit more involvement.
The Crown Prosecution Service are shown having a very active role in client/victim liaison - in reality this role is more likely to be carried out by Family Liaison Officers leaving the CPS free to assess cases and ensure that those taken forward by the Police are most likely to result in prosecution.
Sinead Keenan and Kerr Logan previously appeared together in London Irish (2013).
