I am totally against sulphur burning flares as well as smoke bombs These sulphur burning things don't take no prisioners when they come into contact with human flesh Smoke bombs, I saw what one particular smoke bomb did to a young lad in a wheel chair at the Cardiff City stadium last season. Not sure if the local constabulary could have a few of those cocker spaniels dogs on duty for the Bristol derby on Wednesday night Although I am not sure if the cocker spaniels are based at the horse and dog centre at ashton or they are drafted in from another force area
No more dangerous than a cup of tea. Watch a lot of football abroad and pyro is commonplace. clubs like Willem II for instance organise displays with fans.
