That is what the law says just like in FL but it does not always work that way, ask Zimmerman.
Zimmerman, like any of us who shoot another, will have to convince others that there was reasonable fear for his safety and he legally had the gun.
I did not claim it would be an immediate pat-on-the-back and no consequences. But if the above is shown true, there will be no 20 year sentence as the poster suggested.
