From ABCNews.com: Lawmakers Call for Congress to Probe Bodies Shows in Wake of '20/20' Report

"There is a due diligence that has to be done, particularly coming from a totalitarian dictatorship where execution of prisoners and a general lack of value for human life are paramount," said Smith, who has championed human rights issues in China for many years.

Smith said he will be issuing a formal request to the House Foreign Affairs Committee for a congressional hearing. "There needs to be a moratorium immediately. There is something very very wrong here."

I think the 20/20 investigation has raised a lot of questions in regards to where these bodies are coming from.  Premier Exhibitions says they get them legally, but they never provide any documentation or paper trail to show that these bodies are obtained.  The investigation raises the possibility that the bodies could contain political prisoners purchased off the black market.  Premier Exhibitions just issues press releases but has little transparency.  Only the government can force them to testify and to show any documentation they may have.

Other issues the 20/20 investigation raises which is that the bodies are brought through customs not as cadavers, but as "plastic models for educational display".  This circumvents all the laws regarding transportation of corpses.  How are they able to turn a human body from a corpse into a piece of property?

This should be interesting if Congress opens their own investigation.
