Whoa. Good Question.
Okay, my sense of loyalty would really require me not to snitch.
Then my sense of beingbroke would kick in. I woudl call the fugitive, and see if they could beat the reward (as some sort of incentive to NOT turn them in). If they could not, that would be me picking up the phone...
LOL. J/k. If the person was extremely close to me, I would not call them in. If it was only an acquaintance, yeah I would.
