JoAnna shook her head for a second before speaking. "They are not gangsters. These people don't know who we are. They have families and need to pay bills, and they would never do this if they were not pressed for money. Look at them… they don't even have weapons."
The truth is that while JoAnna spoke with Juan, she felt pity for the man. Especially when he talked how they are doing this only because they are lacking money. It's not that he looked sincere, but it's that he was incapable of lying because of the truth serum. JoAnna was able to see that he is ashamed that he ended up taking this job from Enrique, and if he had other option, he would never do it.
Jeff looked into JoAnna's expectant eyes and he felt his anger melting away.
