So the scenario is a yelling, aggressive male being restrained by his wife is attempting to grab you or items on or about your person and throwing things at you as you are unable to retreat in a dark movie theater? What if this aggressive, loud, threatening guy had grabbed his gun?
That means good shoot.
it was was an argument one that reeves participated in, He took a swipe at the popcorn and missed, reeves took out his gun, he took a grab at the popcorn and tossed it at him reeves shot him.
Its obvious and simple is was murder because he was angry not because of reasonable fear of GBH. His wife who is sitting next to him even says as much before she is told to STFU.
Key thing here is what a reasonable person would think, therefore I don't ever expect you to understand. Dudes wife gets it, everyone else gets it, just a few of the normal posters here don't get it.
