Pushed or pulled, there is no minimum age to belong to a gang or sell drugs in the street for a cartel. Negative outside factors, barriers, and conditions in the social environment such as poverty, family problems, and lack of success in school, there are a lot of reasons. I've been working with different people to help children and teenagers to stay out / get out of a gang by trying to provide them with an alternative, a purpose (youth sport for example). Short-term gang members are generally able to leave the gang without serious consequences. I mostly worked on my own in the streets with former gang members. The first objective was to get their trust. The concept of street-school (article "A school in5' for 0$") was for example a great way to be visible and to introduce myself to random gang & former members. (MS13, Barrio18, TVR, Crips) You have no idea of the work they have to do, and the many barriers they face to get out of it such as tattoos, self image, lack of employment skills, lack of official documents, lack of methods for obtaining a job, personal issues such as anger issues, family conflict, mental health issues, and involvement in substance abuse. My work, I am aware of it, was definitely incomplete with the fact that I could not create a long term link and help. However, I feel that it helped them to find a new start, set goals, identify their skills, qualities and empower their self-esteem. A modest help but priceless for them.
