Jorge Macri, head of the Buenos Aires city government, defended the arrest of subway delegates during a protest on the city's underground network. The detentions followed a police operation connected with disruption of the service. Macri said, "The one who blocks an essential service goes to prison." His comments framed the arrests as support for keeping the subway running. The dispute centered on the treatment of people obstructing an essential public transport service. The episode placed the city government's authority behind the police action as tensions rose around the protest.
