Guy.. I know you’re the expert ... or so your profile says... I’ve got the jury instructions. It is what it is. Maybe you didn’t get to write the law in Oklahoma?
Self defense is justifiable. The cop will not get away with arguing self defense in this case.
Scroll down to the part that it talks about malice a forethought. See how long it takes to establish premeditation. The law is sometimes different than what people may think it is... certainly different than what we may think it should be.
