It all depends under what circumstances your providing the statement. If it's made to the police during their evidence gathering part of an investigation and you've been read your Miranda rights, then yes, you can count on it coming out and in a light that will do the most damage.
If it's while working with the police as a confidential informant, then it is not so easy to get the information, but it still happens. Personally, I wouldn't risk my life counting on anything being "confidential"
Best advice, don't say anything you wouldn't want to be printed in the local newspaper.
