The "higher standard" is what you could face before a judge and jury. Cribbing from Andrew Branca's Law of Self Defense, how would you measure up to the principles of Innocence, Imminence (AOJ), Avoidance (+P), Proportionality, and Reasonableness. Were you bound by Duty to Retreat or protected by Stand Your Ground? Were you in a No Carry zone? This considerations extend well beyond situation awareness and proficiency.
You can argue that Vermont's Constitutional Carry has worked well but will that extend to other states?
Personal responsibilty and judgment are not always stellar in the general population. Does everyone who picks a gun and goes to town thinking about the ramifications? When the situation escalates, are you aware of and apply APJ+P? Not if you are oblivious.
A- A jury can nullify any of those if they feel like it
B- Branca's law is a real law, or his interpretation of a law?
C- How would you measure up given the no one can forsee the accurate future?
D- Retreat or stand your ground - Jury nullification again
E - No carry zone - Jury Nullification -
F - NOTHING goes beyond situation awareness, you cant bring up the 1st 5 parts as a point only to say its beyond SA- What you pointed to, is exactly what SA is.
G - Exactly what part of the 2A states ANY of that is required?
back to the point, Everyone wants to impose their opinion on everybody else, for the "good of the community". If you worried about APJ+P, than that is the ONLY pre-requisite for a CCW, online, and free. simple, live and let live
