For God's sake, are you coming out to Brazil in the next year to see the World Cup? Be prepared. Violence is getting worse - not only in the main cities but also in other towns - and tourists are always potential victims of gangs. And do not think that security will improve during the matches' days; the Brazilian law was written to protect bandits - and not you and me!!
That's my advice: do not be lured by 'naked women', 'beer', 'sex' and 'football', as (unfortunately) those are the adjectives do 'describe' Brazil. You should be concerned about 'robberies', 'rapes' and 'murder'.
Take it into consideration!!
