Ayoob, George Zimmerman trial....
I agree that a Nexus-Lexus search or maybe something from the FBI Law Enforcement Bulletin may have some legal documents or court cases.
Massad Ayoob wrote a recent gun press item on armed citizens & open carry.
George Zimmerman stated to the Sanford police investigators that Trevon Martin saw his Kel Tec PF 9 pistol then said; "Tonight you die, _____ _____."during the violent encounter.
I, for one would consider a gun snatch or a assault to be a justified use of lethal force if the attacker is trying to actively kill you.
The same would go for a Taser/EDW or a impact weapon. Violent felons do not play fair or follow any rules or laws.
They will kill you as quickly as they can.
