It depends on what your definition of "busted" is.
Lei Jin was never extradited and never jailed.
The United States indicts foreign nationals for drug (steroid) trafficking all the time in countries with no extradition policies (busted?).
Lei Jin was never at risk of going to jail. China was never going to send him to the U.S. to face trial. (not busted?)
However, the U.S. "used" the Patriot Act to steal millions of dollars from Jin that was in a Chinese bank + the U.S. pressured China to revoke Genescience's pharmaceutical license.

These factors forced Jin to the bargaining table (for a plea agreement).
Jin (individually and on behalf of Genescience) forfeited the $2.7 million stolen by the U.S. plus agreed to forfeit an additional $4.5 million as part of a plea agreement.

In exchange, Jin was given 5 years probation (and China eventually re-licensed Genescience).
The U.S. used $3 million of the seized funds to pay for anti-steroid high school programs in Rhode Island including those involving Taylor Hooton Foundation.
