Aye there illegal , But if the taigs do it and we do it , does it make us both scum? Calling your own fans scum is a bit much. What about standing? Thats not allowed and even considered dangerous. Standing has killed more than a flare has ever done. So do all football fans become scum because they stand at games? Plus these things happen at away games , will never see pyro in the home end at Ibrox.
