1)No meeting without a LEO and or lawyer. Pop just might favor his kid and take it out on you. Your good deed may bight you.
2)Don't offer a Chinese menu of pick one from col A or B. Give him one choice or refer him to the LEO.
3)As to the choice, it's your call not theirs. If you have a feeling the kid is worth it? Give him a pass and let him ware a sign board " I will not steal" If you already know this was the xxx case a beer he stole, go hard. Next time he may bring a bat,, or golf club,, or 10 of his buds,, or ??? Might not be your place, so think of the next guy.
