The thing is, street gangs are not really a collective entity. The activities of street gangs are incredibly individualized, they are a bunch of criminals who operate under a shared cultural identity, but there is usually no central controlling chamber nor collaboration among groups. Bllods, Crips, MS-13 and Latin Kings are just brands, anyone can identify themselves with one of these brands, and they don`t really have to do anything to become a part of the organization, because there`s no organization to begin with. Bloods cells fight each other all the time the only thing they have in common is their hatred towards Crips. So it doesn`t really make much sense to speak of them as if they are one group. Most of the MS-13 gangs in the US are operated within small circles, they are not the same. Some are sophisticated OC groups, some are your average street-corner drug dealers, it is simply misleading to say that they all did something or they all didn`t do something. I`m sure LCN has been working with some individuals in these gangs who hold valuable resources, but it doesn`t mean they have a mutual agreement with all these groups, most of the street gangs are of zero value to LCN, they wouldn`t bother to contact these small-time groups.
