The system of law in the UK had been developed over many hundreds of years. Yet, Barney was not given a fair trial by any means. Firstly, Barney was not fit to plead, having the mind of a young child. Secondly, the crime was not investigated properly. Thirdly, the reason capital punishment was abolished was that it cannot be reversed. Greg and Abby seem to be so keen to blame Barney as quickly as possible that a mistake was almost certain to be made! And it was. That makes four deaths Abby was responsible for. The three 'Angels' where she took the plague to with no thought and Barney. Although Abby liked to think of herself a leader making responsible decisions, in reality she only thought of herself. Greg was not much better, except he had a loud voice!
