The military is a cross section of society. you're always going to have that bottom 10%.
Even HSLD units have scumbags. They may be a fitter, smarter scumbag but they're still scumbags.

By the way, it is a crime to be affiliated with a gang, according to AR 601-210 it is contrary to enlistment standards to be affiliated with any gang or criminal enterprise. If found you are still in a gang you will be punished by UCMJ for falsified enlistment.
Now, I knew several gang members while I served, two were SoCal Bloods (or whatever) and one was a prospect for the Washington Chapter of the Hell's Angels. We also had two full on AB guys in one of our Forward Support Companies that probably had welts on their tongues because their First Sergeant was black. They're everywhere, hiding among those who all wear the exact same thing. It's unavoidable and I never saw one get a Court Martial for still being tied to a gang. They do however not allow gang affiliated tattoos and racist tattoos- the AB guys were smart and didn't have any obvious racists tats, although one did have the Algiz (looks like an upside down peace symbol) on his neck that is common AB affiliated ink but is a Nordic symbol as well so they can't discriminate against that.
