That would be the RICO Act - Racketeer Influenced and Corrupt Organizations Act. Property acquired through illegal means can be seized.
Hm. I wonder if RICO would be applicable here? They'd have to be charged with two Racketeering crimes within 10 years, from What I've read.
Let's see...The "Garriot Letter" Appeared to have been settled without charges, but there's still the apparent overvaluing of IPs. What else?
*"gambling, murder, kidnapping, extortion, arson, robbery...dealing in obscene matter, or dealing in a controlled substance or listed chemical" seems unlikely.
*Counterfeiting, Embezzlement, slavery, money laundering, and murder-for-hire are also not likely.
*Bankruptcy fraud is definitely not happening.
*Drug Trafficking is unlikely.
*No Copyrights seem to be infringed
*Doesn't appear to be any money laundering.
*Obviously no trafficking of aliens.
*Also obviously no acts of terror.
That leaves possibilities of bribery, theft, fraud, obstruction of justice, and securities fraud are the only things that could possibly fit in their MO. I'm not assuming that they have recently done any of this, but if we're looking for things they could be charged with under RICO, it'd probably be those.
