Quoting OBL, above. "As I mentioned elsewhere on this forum, there was footage on Twitter after the Charlton game of a group of "lads" on a boat on the Thames going under Tower Bridge with a blue smoke bomb and singing Southend chants. Whilst that in itself is not illegal, I would have thought this group of lads are probably worth some scrutiny."
Actually it can be, if they were found in possession of a ticket to the game it could be argued that there was intent to take one to the game which is an offence. If the perpetrator was under 18 then he/she has committed an offence by simply being in possession in a public place when aged under 18.
In fact there are offences that can be committed which would, in normal everyday life, not be an offence but become so as soon as you leave your home with a ticket to a football match, mostly around travelling and alcohol.
It is illegal to let off a smoke bomb in a public place.
Its also actually illegal for an Under 18 to even carry a smoke bomb

2.4 It is also an offence for a person under the age of 18 to be found carrying a firework or flare in a public place. Smoke bombs have the Firework Standard label on them and will be classed as a firework. However, in contrast to legislation around football matches, no specific offence exists for adults caught carrying flares or fireworks in crowded places (such as festivals or concerts) unless it can be proven that they were carried with intent to cause injury.
The last part has also been changed now, they even made it illegal at music festivals this year

We are told that entering the field of play to celebrate goals etc is wrong. Yet we see constantly the likes of Leeds etc on tv piling on the pitch almost every game.
We get told the smoke bombs etc are wrong but again if you are on the various banter boards on face book etc there are countless videos of clubs up and down the country letting off smoke bombs.
This is something that happens every single matchday, if not at roots hall then elsewhere.
Just because it happens doesnt mean its allowed
