Interestingly enough, a Virginia medical examiner has ruled his death to be a homicide (cnn.com) due to wounds sustained in the 1981 assassination attempt, so, theoretically, I suppose, John Hinckley could be looking at a fresh murder charge.
That's fine rhetoric, but it has no bearing on reality. And the reality is more or less as Michrome has stated it. You need only look at the history of Israel from the day it was founded until ten minutes ago. Folks want them dead.
