Offshore protection from US
It continues to amaze me that criminals can sometimes come up with ingenious schemes to obtain illicit funds and then don't use two brain cell that anyone else would in there situation for any other aspect of their "business".
If you're going to try to scam the US - the dominant political, economically and arguably financial country in the world,
0) Don't put all your eggs in one basket.
1) Conduct as much of the business outside of the US and all its allies, which basically rules out all large European countries and affiliated offshore jurisdictions, e.g. Switzerland, Cayman Islands, Panama, BVI. Your best bet is a Chinese, Middle East or African offshore jurisdiction, such as Singapore, Hong Kong, Dubai with non-US and non-EU banks.
2) Use a company or trust rather than personal account and it is also possible to put in place protections that redirect and split funds further to other jurisdictions as soon as any enquiries are made about the account.
Even if all these options are not available at the start of a business, they would quickly become available with $1m to $10m (let alone the $100m in the article) of funds! This is all public information that anyone can research or obtain from speaking to an offshore tax accountant or lawyer. Even criminals (good criminals) can afford and use such confidential services even if they are eventually caught, their capital is safe...
I guess he's learned this the hard way!
