So you think that 'shall not be infringed' is out the window as long as some kind of made up due process is committed.<quoted text>
Your argument is puerile and invalid.
Since those in jail have had their liberty due processed, they no longer have their rights.
American Dictionary Of The English Language, Noah Webster, 1828:
1. Freedom from restraint, in a general sense, and applicable to the body or to the will or mind. The body is at liberty when not confined; the will or mind is at liberty when not checked or controlled. A man enjoys liberty, when no physical force operates to restrain his actions or volitions.
It only takes a tap to send you right off your pedestal.
So, obviously, as long as some kind of due process is committed then the government can certainly take your guns away for any made up reason whatsoever.
