We had an incident regarding SE Asians in NC too; man kills 3 people(his son, ex-wife's BF, and a friend), and injures two others(wife, and friend's niece). 3 other guys were arrested, including his younger brother, whom I know. Turns out, the 4 of them went there to jump the boyfriend, but I guess the ex-husband had other ideas.
They said he used an assault rifle, they didn't specify what kind but I'm pretty sure it's an AK-variant without the stock(I've seen it in person before and from I know that's the only assault rifle they have); but the news are on him regarding him being able to get a weapons permit. If they knew any better, the weapons permit is just for hand guns.
Also, a few months ago we had a Vietnamese guy get shot/killed by another Vietnamese guy over some small dispute; it was at a cafe/store and many of the people wanted no part of it(other Asians), so to say, so the guy had just bled to death.
