Do laws make a country free of fraud? What about countries with lots of fraud laws on the books that are still rampant with fraud? In any case, how would a law on fraud protect you from a dishonest audio seller -- in any country? What are you going to do? Take them to court?
With all the laws on fraud in the US, I have been ripped off more times by Americans than by any others. I think we can all come up with a few instances of obvious fraud in the public sector to debunk the notion that laws on fraud protect anyone -- in any area of life.
Regarding audio, the contrary also applies. Just because a country has inadequate fraud protection does not mean that an audio transaction will automatically go bad. I have done lots of audio business with Thailand without a single problem. In the end, it is the individual who makes a transaction go right or wrong, not the law.
