They may well be found to be 'men of straw' with no worthwhile assets that can be obtained.
If they were prosecuited in Bermuda and hadn't much money to grab, all the Bermudians could have done would have been to imprison them (costing money) or deport them. Even if the credit cards were taken, it may well prove difficult to hang on to any money raised on them. Deportation wouldn't be easy if no airline would take them, so you'd need to find a ship that would.
