"the right to bear an arm shall not be infringed": you can NEVER take the gun of someone in any case.
If a judge wants to take the gun of a prisoner, he couldn't because that would infringe this right.
There's dozens of states where convicted felons cannot own weapons even after they're released from prisons. You can absolutely lose a right even if it's guaranteed in the Constitution so long as its removal is conducted through due process and I don't see how you can interpret it differently.
You're speaking about the current US system? Do you realize the current Supreme Court is full of crazy people like Antonin Scalia and Clarence Thomas? I prefer not to put that in the constitutioin, because this is a utopy to think judges are fair in their judgement, they are appointed after a decision made by politicians who are EXTREMELY under lobby influence, so potentially a lobby of dynamite could rise etc.
I'm speaking about either the current US system or Atlasia's, doesn't matter. No judge is stupid enough to say that any part of the law implies that prisoners can bear arms. Neither Antonin Scalia nor Clarence Thomas - nor any other politician or public servant - want a society where prisons are controlled by armed prisoners. The idea that it's a
realistic possibility that a 'lobby of dynamite' might influence judges to declare that convicted felons can carry grenades while serving their sentences is either deliberately disingenuous or mind-numbingly dense. Your amendment tries to resolve a problem that has never existed, does not exist, and
will never become a problem by adding more language that does nothing other than make the Constitution a muddled mess to a clause that has not been an obstacle to
major gun control in the past. There's neither concrete need nor coherent rationale for it and as such it's a useless piece of law.
