Actually if the libtards learned to read, the would find that D.C. vs Heller explicitly justifies private firearms ownership for MILITARY PURPOSES, specifically quoting Federalist 29.
Furthermore, D.C. vs Heller preemptively finds any ban on commonly used military firearms such as the M-16 to be unconstitutional !!!!
I am surprised someone from our side has not yet brought this up yet ...
They (the supremes) were arguing against having M-16s and somewhat loosening (but not completely severing) the linkage to a militia, but also make an argument for commonly used weapons and accessories.
