I'm really quite upset at this. First we decide to investigate it as a health and safety issue rather than a manslaughter/murder issue and then we decide not to procede on the basis of insufficient evidence, despite the fact that a carriage full of commuters witnessed the incident and an entire chain of command must be able to provide evidence as to who said what in the build up. Whether or not and police should actually be found guilty is debatabe, but without charges and a trial we'll simply never know.
