Dethie returns home after a long day hunting scrap metal on October 24, 2007 in Barcelona, Spain. Illegal immigrants are detained in centres not unlike prisons. They are provided food, water and shared cells, but they have little freedom for 40 days. During this time, the Spanish national police, the Guardia Civil, do bone density exams to determine if they are legal minors, check their health and then try to determine their country of origin. Photojournalists have not been allowed to take photos in any of the detention centres. In most cases immigrants donŐt carry passports. For some, passports are prohibitively expensive and require long waits for processing, with bureaucracy and corruption at every turn. Others choose not to carry any identification on purpose, because they have learned that it makes it more difficult for the authorities to repatriate them.
