As far as I know - unless you are currently wanted for arrest, then there shouldn`t be a problem at all. I don`t even think it`s necessary to declare it, unless immigration procedures have changed VERy much in the past year or so.
I`ve had relatives visit me here who unfortunately had some pretty serious criminal records, and it was never even asked of them.

I think the US is doing a bit of overkill. Cases like yours have been in the news these days - I`ve heard they`ve even refused entry to the US for more mundane things that don`t even involve past arrests.
