Well there are two issues here that I see here, MC. First is, don't do bad or unseemingly stuff on record that you wouldn't want aired publicly, e.g. control thy tongue. People are simply too free and easy with email/ social media, they just don't think of possible repercussions. The other issue security, is more complex but boils down essentially to convenience vs. security, you really can't have both at high levels. The US govt, corporations and public has chosen convenience( in the main ) and considers losses due to lax security to be the cost of doing business. This works until it doesn't, as events like the Sony Pictures hack should have demonstrated in spades. Maybe things will change now, but I doubt it, it's too embedded in the culture.
