I would say that individually, any member who has not been convicted of a felony, who is an American citizen, retains the RKBA, and the others as well.
However few notable examples are not disqualified by felonious behaviour or citizenship issues.
It is interesting to note that an English Dictionary published in the second decade of the 1800s (King George III's son had been made Regent while George III languished on his deathbed) defined "Militia" as "The Army, in its entirety.", and that one of the founders described the Militia essentially as 'all of us'.
The idea that the Crips, Bloods, etc. are defending neighborhoods as an army has serious problems, in that they are an occupying force defending an occupied territory from a rival occupying force, not for the benefit of the citizenry of that territory, but their own enrichment at their expense.
