Crime only pays if you're smarter than a brick
These ten were idiots. You don't use the Internet - a world-wide communications network - to scam people in your own country. Even the bloody Nigerians are smarter than that.
If you want to sit in Germany and scam people, scam the Chinese. Their government can't touch you (unless you're stupid enough to visit Tiananmen Square), and Western governments won't cooperate. Well, except for George W. Bush, who admires the Chinese method of dealing with dissidents.
And there's your IT angle, you gits - this was an *INTERNET* scam. So bugger off, there's a good lot.
