Carry on, you've left several questions unanswered.
lol
Do you think the stewards know anything about horse-riding and racing?
Are you saying that the stewards never get it wrong? That's like saying the FA never get it wrong when it comes to punishing a player. Just a silly question
Why didn't the stewards give him a ban?
I honestly couldn't tell you. Maybe they thought the whole episode was embarrasing enough? As I said, he fully deserves a ban for what he did.
If you had bet on Johnson's horse would you not want him to try and win the race?
I'd like him to take the right course and think whilst he's riding. He didn't do this. He was too late to correct his previous mistake. Yes I want him to try to win the race. Do I want him to do it in a way that's dangerous to other horses and rider (inc his own)? No of course not.
Really, just look back through the incident and explain to me why Heskin gets a ban but Johnson doesn't.
