The police are investigating a classmate of mine for a drug charge and they think I may know something about the charges. I do but I don't want to talk to the police. So a cop came to my house and asked to talk to me and my mom said no. She said we wouldn't talk to the police unless we had a lawyer with us. The cops said because I wasn't a suspect that I didn't need a lawyer and that I should talk to them. So my question is whether I can say no and absolutely not talk to the police even though they say I'm not a suspect? I actually don't know if I did anything wrong because I was with this friend of mine several times when he sold drugs but I didn't have anything to do with it. Thanks.
