During the parking lot scene after visiting the school, some very bad mouth trauma and i believe that teeth are missing as well. It is shown rather graphically
A character mentions that they have been watching the main character, but the implication is "paying attention to their behaviour over a long period of time", not violations of privacy.
Three people are murdered with a shotgun. A handgun is later used to injure two others. Finally, a character dies from suicide by cop. Also, guns are used as a visual threat throughout.
