The military were supported by the families of the victims of subversion, a group created to counter the Mothers of the Plaza de Mayo. This group placed the blame of the Dirty War on the guerrillas, but had few followers. The trials were followed by bomb attacks and rumors of military protests and even a possible coup. Alfonsín sought to appease the military by raising their budget. As that was not enough, he proposed the full stop law, to set a deadline for Dirty War-related prosecutions. The Congress approved the law, despite strong opposition from the public. Prosecutors rushed to start cases before the deadline, filing 487 charges against 300 officers, with 100 of them still in active service. Major Ernesto Barreiro refused to appear in court, and started a mutiny in Córdoba. Lieutenant Colonel Aldo Rico started another mutiny at Campo de Mayo, supporting Barreiro. The rebels were called "Carapintadas" () because of their use of military camouflage. The CGT called a general strike in support of Alfonsín, and large masses rallied in the Plaza de Mayo to support the government. Alfonsín negotiated directly with the rebels and secured their surrender. He announced the end of the crisis from the balcony of the Casa Rosada. The mutineers eventually surrendered, but the government proceeded with the Law of Due Obedience to regulate the trials. However, the timing of both events was exploited by the military, and the opposition parties described the outcome as a surrender by Alfonsín.
