Trauma times two People who experience multilayered traumas or multiple traumatic events that occur in close proximity to each other have a higher risk of developing PTSD. After being shot at and terrorized by extremists for three days inside the Westgate Mall in Nairobi, Kenya, these people were then arrested at gunpoint and interrogated by armed police before being set free. The police actions may have been understandable, but unfortunately served to compound and intensify the trauma for such victims.
