What is Shuswap BC?
Typo or what as I see it as Shu-swap, as in a show?
Anyways, releasing animals back to the wild, especially reptiles, is best left to the pros, the people that are doing specific rehab or breeding, under contract etc... One or two nasties released with the animal can have detrimental effects on many things, like Chuck stated.
As for the kid.. violence is sometimes the only thing respected and will work, but maybe not in this case.
See if he will do a trade, something he wants, like a certain comic book, toy, pack of smokes etc.. (j/k with the smokes )
I highly recommend the hard to find, but easy to care for 'Pet Rock' with its' own traveling kennel and straw nest.
