No I would not turn them in, because it would be to weird for me to turn them in to the police. I would probably wouldn't tell anybody. I would hope that the police catch them but I would not say anything. I would tell them to turn their self in.
I think that personal pursuit is better because i think that helping yourself before others is natural. I think that no matter what you do everything comes back you even if your helping others, because you dont want your life to be out of whack helping others.
