Still, the tournament went on as scheduled and none of the matches were disrupted. He said he expects the same type of response if there are protests this year.
The Black Bloc anarchist protest movement has announced plans for protests of the World Cup, starting with the opening match on June 12 in Sao Paulo. A Black Bloc Facebook page listed demonstrations for June 13 in Natal, Salvador and Cuiaba, followed by six more protests in six cities on June 14 and 15.
Brazilian authorities have said that they've learned from the demonstrations during the Confederations Cup and will not let protesters get too close to stadiums during the World Cup.
In December, Andrei Augusto Rodrigues, security head for major events at the Justice Ministry, acknowledged that police misjudged the threat to public safety in Rio de Janeiro in June at the final of the Confederations Cup.
Police used tear gas against protesters outside Maracana Stadium where the final was held. Clouds of the gas wafted toward the stadium caused vendors at refreshment and souvenir stands to cough and tear up.
Protesters got within 200 (meters) yards of the stadium, packed with 70,000 spectators for the Brazil-Spain final.
Rodrigues has said that police will keep demonstrators farther away from stadiums during the World Cup.
