See post 10?
"In fact, the reason the FedGov hired so many privateers was BECAUSE they were ***already*** armed."
So why didn't they disarm (or perhaps, disordnance?) these men prior to any extracurricular service if only small arms are included in the 2ndA?
They weren't under any obligation to do so. Privateers were not citizens. The letters granted were in support of the declaration of war. You hire folks when you don't have enough. In this case, the Congress hired ships and crews, not citizens. The Bill of Rights is a completely different issue, it limited the power of the Federal government over its citizenry. Two separate and distinct issues.
