I agree, but it sounds to me like this boy just got his snakes. I don't think it's wise to take snakes to public places, but in this case I think there might have been extenuating circumstances. I don't know what the weather is like in Kentucky, but here it is very cold. If I had just bought some snakes and I was given the choice between leaving them in the car or hiding them in my pocket, I would hide them. I would like to hope he wouldn't have taken them out if they hadn't been talking about snakes.
I'm not saying he's right, he should have had the materials he needed before he got the snakes (if it was theorized scenario above), but we shouldn't make judgment calls without all the facts.
