While you are right to an extent re' simply criminalising all football fans, in my experience campaigning against this Act there have been instances where guys have been arrested for shouting "**** Hamilton" yet little more happened as they paid a fine on the spot.
However, on many occasions young fans who cannot afford to do that havery been kept in the cells over the whole weekend with a court case looming over them for some time.
It's nothing to do with the OF. This is about football fans being criminalised for something which is completely legal outside the football ground.
Fans from Motherwell, Hibs, Hamilton, Partick, Hearts to name a few have all suffered from this.
But even if it was simply to keep the OF fans in their place, it's still outrageous. I will take you back to Boxing Day two years ago. A 17 year old Celtic fan had his door kicked down at 4:30 in the morning with his Mum and young siblings in the house. He was taken to the Police Station and kept in their for 4 days. Why? Because he shouted "We hate ******* Rangers" at a football match 5 months previously.
That young lad had to worry for a long time about his life being ruined due to this. Fortunately when the court case finally did come up, it was thrown out by the judge.
So no, it's not ok to simply keep OF fans in check.
