Original sentence: All factors influencing the choice of the host nation like crime, infrastructure and stadia building costs were already known during the selection and voting process so it is unlikely that the decision would now be overturned on these peripheral concerns alone
Edited sentence: Additional reasons for hosting the world cup in another country include, the cost of stadiums, inadequate infrastructure in South Africa, safety concerns of International FIFA supporters (especially considering the actual high rate of violent crime,rape and murder in South Africa), and justification for building the stadiums in South Africa
