researching jurisdiction?

Round-tripping? I have a degree in criminal justice, a law degree, and six years of working in the law enforcement field, and I have no idea what you're talking about.

Do you know where this occurs?

I've worked in law enforcment for 13 years and I've never heard of it either...

ETA: Google is my friend. It appears to have something to do with illegal stock trading. Or some such thing.

From what I've dug up on google, round-tripping involves corporate fake foreign investing as a tax shelter.

I'll see if I can find some links, but you probably need something international (interpol? is that right?).

If you're talking about artificially inflating a stock value, the authority would be the Securities & Exchange Commission. I believe that the violation occurs where the stock is traded (i.e. New York Stock Exchange), where the person is, and where the company is. Enron is an example of round tripping.

Arresting officers would probably be the US Marshall Service, on an arrest warrant out of the US Attorney's Office, through either an indictment or information.

It is possible that local or state police might become involved.

FBI may be involved, especially in the investigative stages.

State attorney general's office may also be involved.

Internal Revenue Service may also be involved, as there is a high potential for tax fraud here.

Best of luck,
