Your making a lot of assumptions. You think kids can't hide shit? OP clearly states that he got caught already and doesn't live with his immideate family. Pretty sure people have an easier time getting away with shit when their not living with their parents. Makes no sense to call the police when this issue can easily be solved by his family/ guardians. You say my option to buy drugs from him is stupid but I don't think ur using ur brain here. Op said the kid was speaking to him about selling drugs casually on social media. So that makes me think they're close in age, and that the kid thinks OP won't say anything. That's when you act all cool about it and say u wanna by some and he'll probably be cool with selling to you. Now the parents have proof and if they want to call the cops or not that's on them. Btw when you call the cops on someone for selling drugs, they have to prove it, social media is not enough to do anything to this kid. So when they do find him and he happens to have no drugs on him you think the cops will arrest him? They need proof as well. Without proof OP best option is to call his guardians/parents/ex.
