M14 Shooter
The Light of Truth
This is exactly correct.The obvious problem that might arise is that no one believes you were actually defending yourself. Then you are accused of murder. And convicted of murder. As we have seen happen recently.
I know of one case that happened. Two men came in to rob a pharmacy. The owner came out shooting. He shot one of the men, the other ran out the door. The owner followed him and then returned to store. He walked over the one man lying on the floor, went back to his office to reload, came back out and shot the man on the floor at point blank range. He claimed it was self defense. The jury called it murder.
If the threat is real, you have the right to self defense. Once the threat is gone, it is no longer self defense.
