I'm not defending the man, all I'm saying is it seemed like a set up. I'm sure the FBI tests quite a few securities attorneys and I'm also sure the majority turn the money down. That is why I am saying this guy was probably in a bad spot with money. I would go as far as to say he probably pissed someone off and they called the FBI and said that he would bite on this bait. Either way he is screwed for making a really bad decision which will in likelihood cost him his practice and some time in the fed hootscow.
The FBI does not have the time, money or manpower to randomly "test" a large number of securities attorneys to see which ones fall for their money laundering bait. When it comes to financial fraud, they only spend their time on essentially slam dunk cases. There is no question the FBI had evidence that this lawyer was already laundering money. So, they set up the sting to catch him in the act and make an airtight case.
