Could there be a law on stolen bitcoins? What if there would be a law punishing those who steal bitcoins and those people behind scam sites? And if so, is it necessary to have such law? I'm just wondering, if there would be such law about stolen bitcoins, it could be a big relief to us bitcoin users. But then, there are so many questions and issues that goes with this ideal that makes me skeptical about it. 
First we must understand that every nation has their own laws and not all countries may necessarily make same law on same subject. Second for enacting any such international law about bitcoin, btc needs to be a mainstream currency in many countries or atleast half of total world population must use it.
Although there must be some legal safeguards for bitcoin users also but I dont think such a interference will come out without any compromise for bitcoin users.
Governments may make it compulsory to disclose your total bitcoin holding etc
