Yesterday's stadium accident in which dozens of South Africans and Nigerians were injured is easily explained.
The match between North Korea and Nigeria was played at a small, non-World Cup stadium with next to no security on hand. Having already attended a match in Zambia where free match tickets were handed out to the local community I have experienced first hand how the nice gesture of free admitance creates excitement, huge queues and a potential stampede.
The moment that many of those queueing outside think that the stadium is close to capacity they begin surging forward in the hope of getting inside before the gates are closed and they remain locked outside the match.
Yesterday's accident is understandable and easily explained. This same scenario will not be played out during the World Cup. Those attending matches will need to pass through three separate security cordens.
It is also worth noting that the stadiums in South Africa are as good as if not better than those we are used to in Europe's top leagues.
