Why it takes more than one amendment

It seems that the folks in DC have trouble counting all the way to 10.


The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people
-The Tenth Amendment of our Constitution

Of course they must have had trouble counting to two for there to even be an ATF.

A well regulated militia being necessary to the security of a free State, the right of the People to keep and bear arms shall not be infringed.
-The Second Amendment of our Constitution

Seems clear to me.
