Outbreaks of violence, several deadly, suggest that fan unrest in Latin American football is spiralling out of control.
On the same evening, there were savage attacks beside a stadium in Palmira, just outside the Colombian city of Cali between America and Deportivo Cali fans.
The next day, a man was shot dead in a confrontation between fans of Atletico Mineiro and Cruzeiro in Brazil.
While academics who study the issue say that the end of coronavirus restrictions, which have been blamed for increases in violence in French and English football, is a factor, there are underlying problems that are being inadequately addressed by authorities.
“There is no way to end violence in football, that should be very clear,” Heloisa Reis, a professor at the Unicamp University of Sao Paulo told AFP.
“But it can be reduced. For that, a very comprehensive public policy is needed,” said Reis, the author of a book about the problem.
Argentina, Brazil, Colombia, Ecuador and Peru have enacted laws to quell excesses by punishing hooligans with jail or even cancelling sporting events.
Some of these initiatives replicate steps in Europe to control hooligans, such as biometric identification or video surveillance in and around stadiums.
After the riot in Queretaro, Mexico banned travelling fans from games, a measure used in Argentina, Brazil and Colombia, and questioned by experts because, they argue, the fans still travel and the violence moves to the streets.
Despite their best efforts, the death toll remains huge: 157 in Brazil between 2009 and 2019, 136 in Argentina in the last 20 years and at least 170 in Colombia between 2001 and 2019.
“The great failure of the policies adopted is that they focus exclusively on the security component,” says sociologist German Gomez, a researcher at the Colombian Association of Sports Studies.
Specialists agree that measures tend to ignore academic studies or social background frustrations stemming from unemployment, inequality or drug and alcohol consumption.
Football matches provide an arena for competition between men to gain power over rivals, especially on their territory, through physical force.
Reis advocates public policies focused on the education of men but she is not optimistic.
“We have lived under male domination for centuries. The male values reproduced are domination, strength, courage. Is there a prospect of ending that? There is not,” she said.
Specialists and fans perceive an increase in violence since covid restrictions ended and fans returned to the stadiums.
“These are the consequences of such a prolonged confinement, in which people, when they return to a public event, need to break out of that confinement,” said Gomez.
In Brazil, at least nine incidents have been reported since February 12, including the shooting dead of a Palmeiras fan and the stoning of team buses, in which players were injured.
