What on earth is your baisis for this totally illogical (and incorrect) statement?
US vs Miller
Heller vs DC.
From Miller:
n the absence of any evidence tending to show that possession or use of a 'shotgun having a barrel of less than eighteen inches in length' at this time has some reasonable relationship to the preservation or efficiency of a well regulated militia, we cannot say that the Second Amendment guarantees the right to keep and bear such an instrument
So looks like you need to bone up a little before spouting off.
No, no, no . . . your quote from Milller says, basically, since there is nothing to show that possession of a short barreled shotgun has any relaltionship to a well regulated militia, then there is no basis for holding that the Second Amendment guarantees the right (to citizens who are not part of the militia) to keep and bear such an instrument.
In other words, this court is interpreting the 2A as only allowing citizens to possess weapons that are reasonably related to the regulation of a militia and, since a short barreled shotgun is not related to the regulation of a militia, then citizens cannot legally possess one.
Your interpretation of all this is simply incorrect. You are twisting this around to argue (illogically) that since the 2A only applies to the regulation of a militia, then citizens (who are NOT part of the militia) should be allowed to bear the same type of arms as the militia itself. This makes no sense.
