When it is attached with a football match, yes I do hold the club responsible.That's because you're a decent person, but it's not really what I was asking. Do you hold clubs accountable for all crimes that their fans commit regardless of if they were on match days, or had anything do do with football?
Clubs should be responsible for ensuring their fans behave inside their ground and for advising them of their expected behavior. You can't make them responsible for everything they do outside of the ground, especially incidents on a non-matchday or miles from the ground. I just don't see how punishing everyone in the ground will help in those situations?
