Yes it does, learn the referee instructions. Serious foul play in terms of a tackle doesn't have to be deliberate. In order to get sent off for a swinging arm the ref has to be certain it wasn't a natural bodily movement and the intention was to hit the other player - I.e. it has to have been intentional, which means deliberate
See above - depends on the manner of the foul play. If it's off the ball violence, it has to be deliberate.
Intention to hurt the opponent is irrelevant for serious foul play and violent conduct. Learn the rules.
How on earth he didn't give the penalty for the Bradley Johnson handball is beyond me, he was ****ing looking at it from less than a metre away. Bald clueless ****.
Seriously you haven't a clue. You are conflating two very different offences. You don't need intention for serious foul play. Violent conduct is completely different. It is impossible that intention to commit violent conduct is irrelevant to be violent conduct given that the mens rea of violent conduct is intention. If there was no violent conduct, it would either be careless or dangerous, it cannot be violent. That's why you can perfectly legitimately break someone's nose and not get sent off if, in swinging your arm, you were neither acting recklessly nor intending to hurt. You obviously need to learn referee's guidance. Intention is imperative in off the ball incidents.
