first:
I hope I reach allinvain, which got stolen 25.000 BC...this forum anti-spam is annoying, I can not even write him a PM.
ok:
so, what I would do if I got robbed of my bitcoins:
1. Persistently trace the transactions of my stolen BC through blockchain (should be possible)
2. Publish a list of these transactions every day publically, especially here on the forum
3. Sue everyone that I can get hold of for concealment of stolen goods. (You can always know who got your stolen coins through blockchain)
Point three especially applies to money exchanges like MtGox.
E.g.: Someone cashes out any of my stolen coins at MtGox => If MtGox cashes out, sue them for concealment of stolen goods and claim the BCs invovled.
Fortunately I don´t own any BC, so that is one concern less.
