I have had to question people that have mirdered others and their family members. Before they ever confess, they might rock, hold themselves with crossed arms, get really thirsty, and smile. Even when they talk about their crimes, sometimes they smile. It is really disturbing because their body language does not reflect how you think most people would behave having killed their family members. Yes, most people behave with sadness, remorse, grief, crying, devastation, but not all of them. The ones that smile, it almost seems like they want you to like them. This is my opinion based off having to question people who have committed crimes.
