I can't. I think criminals will find their way with Bitcoin or without it. It's easy to fall for the easy argument: "the standard banking/monetary system is even worse, so bitcoin is ok". As a small example HSBC was considered too big to jail (they laundered last year about twice the size of the Bitcoin Economy, helping criminals, drug lords, etc), and only got a slap on the hand (a $1.8bn fine). The powerful can launder their money, do tax evasion, use tax havens ... now it's available to all technicaly skilled ones (good or bad?). Drugs sold on silk road were evaluated (http://arxiv.org/abs/1207.7139 http://arxiv.org/abs/1207.7139) last year to about $14m/year ... a good 20% - 30% of the bitcoin Economy, so yes it's looking pretty tainted so far. I would however highlight one innovative point: If you slip (leave any trace, don't use TOR, use a physical address, leave your IP), the community can track you down! And I think it will happen. Because ledgers are public, you can make algorithmic criminal enforcement :)(for those criminals or corrupt politicians who are not careful enough)
