I don't want to step into whether Barbara Sheehan shot and killed her husband out of anger over alleged infidelities, or to end years of abuse.
However, the legal system abused her by acquitting her of murder, but convicting her of "illegal weapon possession." Welcome to New York folks, where you can use a handgun only if you meet a lot of narrowly defined criteria and bow at the alter of the pistol permit bureaucracy. No exceptions seem to be allowable for exigencies of any sort.
Damn you all to hell.
