Re: Hearings On "Stand Your Ground" ...
The USA has 50 states and several more territories that have their own laws and court precedents on the use of potentially lethal force, in defense of oneself, others, and property.
These laws and court rulings are usually similar; but can be and often are significantly different; and are frequently changing over time. Reactions to situations that would have been deemed justifiable, some years ago, are now crimes; and in a few states, reactions to situations that would have been crimes, several years ago, are now justified under statutory law.
At least one state (Texas, if it has not very recently changed) seems to still allows the use of lethal force to stop some property crimes. In other some states a situation that would have been a "stand your ground" justifiable homicide, becomes second degree murder if the person who is compelled to use potentially lethal force is found to have behaved in an overt manner that provoked the situation that put the killer in a "likely kill or likely be killed " situation.
Things are as they are. What we, as individuals, think is right or just, simply does not matter.
One would be wise to know the laws and court precedents on the use of potentially lethal force in all states where one spends much time.
MORE IMPORTANTLY, ONE IS WISE NOT TO GET INTO ARGUMENTS (OR EVEN VERBAL DISCUSSIONS) WITH PERSONS WHO ARE POTENTIALLY LIKELY TO TURN VIOLENT. If a discussion becomes heated, one is well advised to say "Your are right" and get away. Otherwise, you could be facing second degree murder charges if the enraged fool draws a gun and you have to shoot him/her.
I once worked for a native of Sicily in Detroit, named Vincent, who had a number of interesting, useful, and wise axioms that he lived by. They included: "SILENCE MAKES FEW, IF ANY, MISTAKES"; "TEACH YOUR TONGUE TO SAY: ""I DO NOT KNOW"" (OR REMEMBER). "OPEN YOUR WALLET AND YOUR MOUTH WITH CAUTION".
All of the above are especially good advice when dealing with persons who might turn violent.
