There was no criminal intent to kill that man.
Amber said she pulled the trigger with the intent to kill.
She said that on the stand.
She did not have to take the stand.
She is responsible for her own incompetence.
Even Shep said a few minutes ago that she admitted to the intent.
The intent was a legal intent to defend what she believed to be her home according to Texas' castle doctrine.
The intent was not to murder an innocent man who had done her no wrong.
Yes, she intended to kill him, but she thought she was killing a burglar who broke into her apartment. This makes it a legal intent, not illegal.
