If the police are questioning you in a professional capacity, telling them ANYTHING is NEVER in your best interest. This child and his parents learned that lesson the hard way.
The job of the police is to show that they are doing something about crime. They do that by finding reasons to arrest people. If you talk to them long enough, they will find a reason to arrest YOU. There are those who believe that telling the truth will help curry favor, or get the police to cut you a break. More often than not, you give a cop who had nothing on you enough evidence to take you in.
Shut up, get a lawyer, and let the lawyer do the talking. Anything you have to say that will prove your innocence will still prove your innocence a couple of hours later when the lawyer gets involved. Police receive hundreds of hours of training in how to use your words against you, so keep your trap shut.
