Prosecution proved that she knowingly and repeatedly lied to the FBI about her trade. Why would an innocent person, who has nothing to cover up, do that? Why did Bacanovic go back and doctor the trade documents (as proven by Secret Service forensics) if he and Stewart had nothing to hide?
I agree. The person who was at fault was her broker, who had no business telling Martha of any insider information. In a way it is kind of like entrapment. Martha did not go out looking for insider information, it was placed in her lap by her broker.
