There is no evidence that Byrd was in actual danger.
Did she attempt to dis arm him? Did she try to strike hin with a skate board.
For a self defense plea there must be some kind of attack on you personally or those in your vacinity.
She may have attacked at a later point, but hadn't at the point she was shot.
That is what yoy libtards enjoy referring to as taking on the role of Judge, Jury and Eecutioner.
Byrd was skeered. Probably Pi**es his panties, but there was no active atack.
