Why do prisons in California and Texas have so many gangs? Why didn't they exist prior to the 1950s? What happens to somebody who leaves the prison gang? How much influence do prison gangs have over people on the streets? I sat down with Professor David Skarbek who has published extensively on this topic. His book, The Social Order of the Underworld: How Prison Gangs Govern the American Penal System, can be bought here.
