We also do not know whether this is a first time offence, how do we know that the Guard and Mr Main may not have had prior history, he may have been a serial offender. As far as I knew Scotrail didn't do penalty fares, the BTP are at least 20 or so miles away and when asked if he needed assistance the guard said yes, in effect making the big man an agent of Scotrail and removed the offender who was (i) Drunk and Abusive in front of children, (ii) Refused to leave the train when asked, whether or not he had the correct ticket if you are asked to leave a premises or property by an official person even if without reason, most sane people would leave especially if you were holding up quite a few people, most of us would just accept it and make a complaint in the morning, this guy thought he was invincible and therefore had the f**k you all mentality.
From what I can see in the video, the bag follows him out about 5 seconds after he was ejected and there was no marks on his face, as the big man moves him, he stumbles, he is not pushed to the ground, from the stance of someone who used to manage an Edinburgh City Centre bar and had to put up with idiots like Mr Main on a near nightly occurence, you sometimes do not have time to think, what if the guy had got up in front of this woman and her kids, pulled out a knife because he was invincible and stabbed the guard, it would be a totally different story then, you have to make the call, he was maybe in a sense to the big man a threat to the guard with his behaviour and if that was the case then the big man had balls to do it.
Also some people seem to forget that Mr Main's Facebook page is gloating about it and the story that he/his father/ and his cousin have told the media changes on a day to day basis, when he knew he wasn't getting anywhere the diabetes was being used for his actions, then the alcohol, then when that didn't work one story going about stated that he had posession of the right ticket, if that was so then why isn't it on the front page of every paper in the land showing his innocence, because he later said that he was issued two singles for the same trip, this kid is trying to get out of it as much as possible, he probably knew if it got out his father would give him hell (apparently the father is a minor celebrity as he sells stuff on QVC and thinks that that will help the case) so decided to make up a story saying he had the right ticket.
I am sadly expecting though the Guard to lose his job before he retires and possibly some of his pension, the big man will probably get a fine or if the PF feels he needs to make an example of the guy a suspended sentence which will probably mean loss of his job and Mr Main will probably come away with lots of money in compo from Scotrail / Big Man and TV or Paper deals selling his story.
