Reality Tv: If you were asked to create one..

I would create one about commiting the perfect crime. Have a scenario set up and have two teams try to accomplish the goal of the crime(i.e. robbery, murder, kidnap, etc...). Then have a forensics team come in collect the evidence of each team(the forensics team doesn't know which team went when). And see who left the most evidence behind and who commited the perfect crime.
