Tahah said, while at a bar, after his girlfriend threatened to leave him to date other guys, he just couldn't stand the thought of her with another man. So he went home, dressed himself in all black, went to her house with his gun, snuck around behind her bedroom, hiding out by the bushes where he could see her inside, then held his gun up, pointing it at her from outside the house,
to scare her (as if she could even see him).
But then......all of a sudden.....brace yourself....
The (loaded and cocked) gun FIRED, all by itself! 
WOW...An ex-police officer who was heavily trained on how to hold/use/fire his weapon...and the (loaded and cocked) gun went off accidently....while he was pointing it at his girlfreinds head....after she threatened to leave him....
hmmmmmm
Any potential jurors buy that? What do you think his chances are of selling that story to a jury?
