> am I obstructing an investigation

If the investigation was legit, then yes. You should just say no. If you give the phone over to them or delete data on it after they ask to see it, you are destroying evidence. Does not matter whether you are the target of the investigation or not, they think you have evidence, you deleted it.

Just say no to the police and then keep your trap shut. This is especially true for federal agents.
