I find that hard to believe. We are thinking of the same Anarchy right? The metahuman supervillain that hates all forms of government? Seems like the exact sort of thing he would do. And it can't just be an accident, either, Roy has nothing in his arsenal capable of dismembering someone, especially by accident. Besides, losing his arm to a villain is kind of Roy's thing, he just wouldn't be Arsenal without the missing arm fueling his anger.
