Question: How is a gang like a social club or family?
Answer: Gangs protect, support, and care for each other. If you are ever in a tight spot, your brotherhood/sisterhood gang will always find ways to save you. Gangs will keep their mouth shut or guard you to keep you out of trouble. They are strictly loyal and they would never bring you down. Like a brother/sister, gangs would literally fight/beat someone up who hurt or bully you. In the "family" of the gang, anyone is expendable. "Loyalty" is demonstrated through the street code of "don't snitch" or inform. When a gang member is incarcerated, his so called-family is not likely to be at the ready to assist him, help his mother, or look out for his little brother.
