>need to be fined, jailed (30 days+)
destroying or tampering with government property or evidence needs to be a hell of a lot more than 30+ days in jail.
That's not even a slight deterrent for future criminals.
REPERCUSSIONS need to fit the crime.
It's not about "losing/destroying an email". It's about the consequences of that email no longer being available. The punishment needs to be based on that.
