What is it evidence of?
Murder?
Manslaughter?
Self defense?
How does one know?
During that time of investigation is it proper to arrest anyone?
Yes, thank you for realizing that there are different situations, which is my whole point.
There are some cases which are so plainly self-defense that no one in their right mind would dispute them. There are also some cases that are so clearly murder that no one would dispute that.
It's the middle ground that causes problems.
These "Stand your ground" laws seem to be a reaction against certain laws or court decisions that imposed a positive duty to retreat in any confrontations. This "Duty to retreat" created situations in which people who were engaging in what most reasonable people considered to be self defense were charged with criminal offenses. Such situations created an outcry that lead to these "Stand your ground" laws.
My position is simply that, while imposing a "Duty to retreat" may have created a ridiculously high barrier to claims of self defense, these new laws constitute an over-reaction in the opposite way, and have, either by design or poor implementation, created a ridiculously low barrier to claims of self defense.
You've got a situation in which an innocent man was gunned down with no warning, for doing nothing more than yelling at a guy who almost hit him with an SUV, and people are actually defending the shooter, and worrying about how "His life might be ruined".
If you can't see how ridiculous that is, and the danger it places everyone else in if such a low barrier to self defense claims are widely accepted, well, I hope you never get into an argument with anyone. You just might scare them enough to get shot, and have them walk away from it.
Seriously: If yelling "Watch where you're *********** going" is sufficient reason to justify deadly force, what's there to stop me from just shooting anyone who yells at me? How about if he's just "Eyeballing" me? There are people out there who think being looked at is a challenge or threat; why should their "fear" be taken any less seriously than that of a little old lady in her house when a crackhead breaks in?
Answer: It should be taken less seriously because
that's *********** ridiculous.
But enjoy your pendulum swing while it lasts, gunslingers.
