*There is an intoxicated girl causing a nuisance on a train station
*The train stops and she leans against it
*The guard sees the girl but tells the train driver to go anyway
*The girl falls through the void between the carriages and is ran over. The guard was then found guilty of manslaughter.
The girl was off her head, she shouldn't even be out in a public area but the guard is there to keep everyone safe. Its hard to say with such little info.
