Why does a 17 year old have an illegal fire arm? Do criminals who have shot someone get to use self defense as an excuse for shooting more people that are trying to stop them?

In many US-states, if a convicted felon (barred from owning a gun) uses a gun in self-defense (say defending against an intruder) they can still be charged with illegal possession. In fact, even more stringent, say their spouse used the gun, and the felon had access to it, they can be charged with what's called constructive possession of a firearm.
