Eddie, all of which leaves the problem of what you can charge him with. If you charge abh or s20 (if it were s18, the killing would be murder) that means, technically, he should really be charged with manslaughter, and it might invite comment that you have stuck him on some lesser charge to get a plea of guilty to something (as if prosecuting, we would think of such a thing LOL). If the evidence is only what we know of, it really is not at all runnable, only barely worth an assault charge and any counsel offered a let out plea would tell the prosecution to get stuffed. After all 'sort him out' could mean a lot of abuse but the anticipation of a fist fight, not necessarily one in which the defendant struck the first blow, and it's hard to see that the person taking the items is meant to be intending anything unlawful, beyond a reasonable doubt.
