Some say all individuals. I say the evidence points to only those individuals who were members of a well regulated Militia.
Given my general definition, that right, today, extends to women and nonwhites. It also extends to the arms in use today. (The latter was confirmed by the Miller court.) But it still only protects the right of individuals as members of a well regulated state Militia from federal infringement.
"they may well say that our civil liberties can be infringed if local situations warrant a type of ‘martial crackdown’ for public safety"
The Parker court admitted that even if it is an individual right it may still be regulated.
As it relates to "disciplining" the active duty militia or in providing punishments for actual crimes committed while in possession of "arms". It says nothing about regulating private firearms ownership for non-criminal uses.
In fact, the entire case is that RKBA is an individual Right and that legal uses of firearms are protected from blatant infringement by localities like DC.
