Demanding and crying Ayotzinapa lives! and Mexico mourns but is not dead! members of the Mexican community in Pennsylvania gathered outside the Mexican Consulate in Philadelphia, in Old City.

The unofficial group "The Mexican Community of PA" met Nov. 9 and 10 in support of the 43 missing Mexican students demanding justice from the Mexican government.

"The students represent the pain of an entire community. We have had enough, we are the voice of those who have been killed," said activist Mark Urbiña during the protest.

The group is formed by Mexican residents in Philadelphia, Allentown, Easton and Norristown who are concerned about the violence and lack of accountability in the Ayotzinapa case.

During the demonstration, leaders of the group delivered a letter  addressed to the Mexican government demanding justice, or otherwise the immediate resignation of the president of Mexico, Enrique Peña Nieto.

Mexico's consul in Philadelphia, Carlos Giralt-Cabrales confirmed that he sent scanned copies of letters delivered by the protestors to the Ministry of Foreign Affairs of Mexico, with a request for further dissemination to the President.

"First, we agree that the disappearance of the 43 students is an act that all Mexicans condemn. I join in the voices that are expressing solidarity with parents, relatives and friends of the missing, and I share the grief felt by our community," Giralt-Cabrales said.

Protesters accused Peña Nieto’s government of negligence. "These are the demands of Ayotzinapa: action or resignation."

The Director of Human Rights Watch for the Americas, Jose Miguel Vivanco recently visited the families of the missing students. In an interview (see video)  with Jorge Ramos, he stated that in “Mexico impunity is the rule."

"There is an obligation of the state to react, to prevent, to save lives. Not only do they not do that," Vivanco said, "the president responded four days after the disappearances, and stated that the problem wasn’t his but the city of Iguala’s, which is three hours from Mexico City."

Vivanco said that there are 90,000 dead, 25,000 missing and thousands of people tortured since the administration of former Mexican president Felipe Calderon.

"All this with a passive State that does not provide results. This will not be solved with a resignation," Vivanco said. "It can be solved by taking the issue of human rights seriously. Hopefully something good will come from this tragedy, that will depend on the capacity of Mexicans to demand public safety," Vivanco said.
