We just need Congress to pass a bill with a lifetime ban on government employment  (and pensions) and with jail time for anyone caught using a private email or purposely misspelling words to prevent FOIA requests.  I'd say minimum of a year in jail with an additional week for every email that doesn't follow official rules to aid FOIA requests.  If there were real consequences, they'd be more likely to obey the rules and also try harder to make sure there are no "accidents."  Same, except with a 5 year minimum jail sentence for destroying or discarding equipment to make data unrecoverable.
