With El asesino que no seremos. Biografía melancólica de un pandillero („The Assassin We Will Not Be. Melancholic Biography of a Gang Member“), the journalist Federico Mastrogiovanni has written a biographical chronicle of the life of Edwin, about his past in a gang, his experiences in numerous US correctional institutions, and his return to life outside. Edwin spent most of his life in the United States, where his single mother had found work. She could not dedicate much time to her children, and in their neighbourhood it was common for young people to form street gangs. The gang was like a family, the only thing that was safe. Violence and even murder was the order of the day. Then one day Edwin stabbed someone. During his years of imprisonment, Edwin, with an iron will, takes the time to educate himself and to train. Having served his sentence, and against all odds, he is able to build a second life from nothing, far away from his family: He works as an English teacher in a good neighbourhood in Mexico City, in a country that is new to him, and which he must get used to, now that he has been deported for life and has no possibility of returning to the United States.
El asesino que no seremos reflects on the discrimination against Mexicans in the United States, addresses the inhumane violence of the prison system, especially solitary confinement and the deportation of undocumented Mexican offenders.
