Guard takes on yob and is sacked and arrested

What happens when you are a security guard who stops a yob from terrorising train passengers? If the experience of Paul Yarwood is anything to go by you will be sacked from your job, forced to sell your home because you can no longer afford the mortgage and be arrested and sent to court for threatening behaviour while the yob gets £80 for smoking in a public place.

Am I the only one that thinks that this is extremely stupid? It seems I am not the only one because his union is defending him and has already staged two local strikes which have been unsuccessful.
