Global witness went undercover. Their investigator posing as an african government minister. Steve croft has part two of the 60 minutes story anonymous. Good to see you. The undercover investigator who called himself ralph kaiser told the lawyers the minister used his official position to collect special payments from foreign companies. He wanted to move the money to the United States to buy a house, a jet, and a yacht. So, wants to bring in the money. So, started with the brownstone. And then probably, buying gulf stream jet. He wants to commission the building of a yacht and property. The story was intentionally devised to raise red flags and lead the lawyers to believe that the ministers money was dirty. During the meetings. Only one of the 16 lawyers, jeffrey herman, told him no. My standards are higher. Reporter the rest expressed varying degrees of interest with most offering advice on how it could be done. We do everything. There is no limitation. We dont say, oh, we dont do windows. Or, we deal with the financial money managers, whatever. No, no, no. We orchestrate and organize the entire thing. We are happy to take that responsibility. What is important to point out it canbe overstated is that none of the lawyers we have shown you broke any laws. In part, because the african minister didnt really exist. There were no hundred of millions of dollars and Global Witnesss representative said no money changed hand. This is sort of a morality test . It wasnt. It was a test on the system. People could make the argument, all the guys did. Listened to this guy in their office. Didnt make a deal. Need to sign up. We need to do research. They would be right to say that. They need to say something. Those lawyers laid out in considerable detail, a myriad of different ways to bring money into america. Reporter none of the lawyers agreed to take on the african nor were they asked to. It was preliminary that ended with most attorneys expressing interest in continuing the die leg and some enthusiastic about landing the business. Give me a chat when it is possible.

I could imagine. 1 million. 1 million. Anything goes wrong. Painful. But it wont be like. Exactly. John jankoff and partner Lawrence Gabe offcamera also orchestrate it one legal fee cover everything. Gabe did express concerns about the transactions. Who can set up the structure, could you do it . Okay. I dont think he does it with money that may be questionable. We have to find out about. At end of the meeting they look forward to the next conversation on the telephone not on email. Give me a phone number. Sending an email with an outline. I dont like emails. Thats how you catch people. The hidden camera tapes raise all sorts of ethical questions not just about the behavior of the lawyers but about the methods used by Global Witness in making them the we showed the footage to bill simon, law professor at columbia university, one of the countrys i think its, draw as tension to the fact that lawyers may be playing an Important Role in Money Laundering that requires more scrutiny. Have you ever seen anything like this before . No. Never. Never. What is your overall impression of it . Any lawyer is big to be any lawyer is big to be uncomfortable. This was a sting. Somebody lied his way into a Lawyers Office and secretly thought he was making to a client. Thats kind of unprecedented and about confidentiality. On the other hand. I think that the tapes expose conduct of great public consequence. Valuable the public sees it. Yeah, very valuable. Confidentiality. Lawyers benefit from it. Under the protection of confidentiality, is never scrutinized by the public. Lawyers are never accountable for it. So the sting actually brings some accountability to conduct in its own report, Global Witness includes an opinion from two legal ethicists including bill simon of columbia. It says that if attorneys mark koplic, john jankoff and gerald ross had been responding to a real request their conduct would not comply with professional responsibilities of lawyers. It said the attorneys displayed a cynical, and evasive attitude toward law. The ethicist also noted that the rules were vague and we do not expect that all lawyers will agree with this. Simon put then aba president james silkenaught and Hugh Finnegan in a different cat go, even though they provided advice on how to move questionable funds into the u. S. What makes him different from other lawyers . He was quite clear he would not assist illegal conduct. He indicated at one point he would report the client if he found the client engaged in illegal conduct. That he would need more information before he agreed to represent the client. Reporter on the other hand he clearly seems interested in this. He clearly seems interested and enthusiastic about it. Reporter anything wrong with that . I find it regrettable. But i am not sure as a professional responsibility, authority, could say inconsistent with duties under the only lawyer who fulfilled the ideals was jeffrey herman. Listened to the pitch, decided it probably involved, illegal activity and ended the meeting. This aint for me. My standard are higher. Not interested. Do you know anybody who would be able . I dont think so. And i wouldnt recommend either. Yeah, yeah. Because those persons would be insulted. You can see the full twopart series on our website. Cbs news. Com. Back.
