TAMPA - A man accused of leading a ring of people who grew marijuana inside homes was entrapped by government snitches, his attorney told jurors in U.S. District Court on Monday. Herbert Ferrell Jr. is a legitimate businessman whose company, Dermal Screening Center, was "his pride and joy," said defense attorney Joseph Bodiford in his opening statement for Ferrell's trial. The company performs screens to detect skin cancer in its early stages, Bodiford said. "His dream was to save lives," said Bodiford, who added that the dream was motivated by Ferrell's own experience with skin cancer. Assistant U.S. Attorney Anthony Porcelli had a different view of Ferrell's motives. "Greed and weed," the prosecutor said. "That is the story of this case." Porcelli said Ferrell wanted to get money from growing marijuana to put into his company.
