I hate to defend those criminals but to be fair the 2.3 trillion didn't go "missing" but was simply not "properly" documented or audited. Thus some of it falls in the category of sloppy accounting, some of it for secret government programs(funding terrorists for example), and some of it perhaps stolen with corruption. This "accounting" crime covering up other crimes being announced the day after 9/11 is of high suspicion and completely understandable why they would hold off for an opportune time to admit such irresponsible lapse in accounting which should be considered criminal.
This huge accounting error makes me question how efficient states are at war and killing people as I used to assume they were very good at these tasks. It is a tough call whether this sloppiness is deliberate and doesn't take away from their efficiency at destruction or just incompetent. My guess would be a mixture of the two.
Either way ... here is a way to earn some BTC and show solidarity against state corruption -
