Re: No defence?
Surrounded by 10-12 folks in a semi-unified group ... yeah, never saw a thing coming. Right. When was the last time you were surrounded and did not have all kinds of 'spidey-sense' bells going off? Common sense is a prerequisite for any successful violent encounter.
I can't even hang out with that many of my own family without getting twitchy.
I'll bet there is quite a back story to all this that put things into context that might even make some sort of sense.
