Regardless of what you think about Britain's membership of the EU (good, bad or indifferent), one implicit benefit for anyone with convictions is the freedom to travel (and live) in any EU country.

Given all the political noise (and Daily Mail articles) about wanting to turn back foreign criminals and not let them into Britain, I'm sure if the referendum votes to leave the EU we will see a quid pro quo and travel restrictions getting much tighter for ex-offenders.
