Is it really Nortenos in the DMV?

I stay in Laurel MD and Im SGC I ain't in a Mexican gang or nun so I ain't really too familiar wit they structure or how they move but there's these Mexicans that live down the street from us and they always be rockin red clothes and shi so I thought they was bloods or something but we don't got no bloods in this area nor do we have problems wit any and one of em got a bald fade wit a mf ponytail in the back and I asked my big brudda if they gang bang and he said yeah they Nortenos or sum shiii and I looked it up and it don't really say nun about them bein in Maryland fr but it say they in VA in the North part in Arlington n Manasses so I think they moved up here or sum shi but Ion know fr and I asked here cuz mfz on Reddit don't really be knowin they shit and them Nortanos be writing on the wall like NSL XH or some shi but Ion know what that shit mean cuz I looked it up and I couldn't find out what it means (edit: i thought it said NSL XH it really said NSL X4)
