Once again I think this is quite subjective and is probably along the lines of the other example I gave.

- This criminal had chickens from galadon, everyone else has chickens, they must have all aided them

I think the level at which people leave stuff piling up trying to draw this conclusion for a flag would be an extremely flimsy one at best.

BUT

For the sake of argument lets say this was one criminal warrior and one non criminal warrior. And the non-criminal left the strange bracers behind in his "random kiling" and they were later picked up by the criminal who happened to wander past that to me a more reasonable thing to consider being aid.
