Thats the same logic you (I,we) use when we carry a spare tire in our vehicle. EXCEPT I'm not scared of the flat tire or the convict, it's just prudent to use caution when past events dictate the need. Gun ownership is like credit...poor judgment limits your access. Or didn't you know that "rights" can be lost if used improperly, just ask any inmate. Law and ORDER does not have to equal Nazi.
I agree with the first part - I carry a gun and a spare tire, basically for the same reason (to be prepared).
I disagree with the second part, keeping and bearing an arm is a right, not a privilage like getting a loan or credit. Yes, inmates cannot have a gun in prison, but they still have that right (!). When a citizen has gone through due process (tried and convicted) his/her rights are legally surpressed, or "annulled". The convict still has the basic right.
This is exactly the same concept where the Founders wrote that "they acknowledge" these rights as pre-existing; the Constitution did not "give" these rights to the People.
Because of this, we have some interesting ramifications. I am sure most of the people here are familiar with the fact that if you get mugged and try to sue the police for failing to protect you, you will lose in court. The police have NO responsibility to protect citizens, their responsibility is to enforce the law. Individuals have the right and responsibility to defend themselves.
However, if a law-abiding citizen is summoned to court, he/she cannot bring a gun into the courtroom. Their rights are "temporarily annulled", much like a convict in prison. As a consequence, if this citizen is assaulted in court he/she CAN SUE THE STATE FOR FAILURE TO PROTECT THEM. Why? because if the state legally surpresses the citizen's unalienable right it must assume the responsibility that goes with that right.
So, in a nutshell, prison inmates do have the right to keep and bear arms. This right is legally repressed by the State and therefore the State must assume the responsibility for the welfare of the prisoner.
Thus, when the prisoner is released, the State gives up the responsibility for the welfare of the citizen and that citizen should therefore be able to excersize all of his/her rights...including the right to keep and bear arms.
