cops are useless when it comes to bitcoin thefts.  they 1) dont know what they are, the equivalent to saying "my friend stole my neopoints" and b) dont have the means to trace ip addresses that are likely outside their jurisdiction.

if you have $25,000 kicking around, then you might be able to get something done, but even then... look @ projects & coinabul... over half a million in one case and over a quarter of a mil in the other, full disclosure of bank information... and yet... nothing.
kind of blows my mind and illustrates the strengh of bitcoin as well as the downside.
