Amy Free to Headbutt Again

Amy Winehouse was released from prison this morning and given a formal caution after an incident in which she allegedly headbutted a guy outside a London bar.

She wasn't charged in the incident -- but across the pond, a caution means the incident will stay on her record and could be counted against her if she is ever charged with anything like this in the future. What are the odds that will happen?
