Jack Boys 

A street gang created in the suburbs of Chicago. All they did was rob drug dealers. It is said they have stolen over $600,000 of drugs and drug money. After making hundreds of enemies from all different fractions of opposing gangs, they decided it would be more profitable to sell drugs rather than steal them. They held on to the name Jack Boys so that people knew not to fuck with them. They ran under the five point star but had affiliations with the Conservative Vice Lords and the Gangster Disciples. Eventually the 3 leaders of the Jack Boys all got sent to jail. The remaining members fell off because of lack of leadership and little money coming in. The Leaders Stay loyal to their nation to this day, even though they have done years in jails and prisons.
