No one survives unless you are thinking of survival in some theological sense, therefore it can not be a right.

Self-preservation is a natural urge and involves self-protection, which was long considered to be at the root of natural rights. It was the basis for the rights enumerated in the "Bill of Rights." It is a one sided view since it considers only the natural rights necessary for protection from the state, or human beings and any assemblage of human beings. The other side of natural rights involves the urge to do well and be well in relationship to other human beings. On an individual basis it means to encourage, to be considerate and to care for the wellbeing of others, whereas on a societal basis it involves social obligation (contribute goodness to society) in that regard.

Self-protection is a natural right afforded by the human condition. If a person places their self in harms way without the means to protect themselves, they could be said to be implicit in a crime resulting from those circumstances.

By what authority does the US government restrict or infringe any such right to self-protection by sane and law abiding citizens, thereby placing their well-being at risk of harm, or greater harm than when self-protection is unrestricted?
