A study from University of Illinois at Chicago has found that witnessing the arrest of a household member can traumatize kids psychologically

Even after accounting for other factors that might explain the condition, such as maltreatment or child abuse, the elevated symptoms associated with PTS remained, the study found.
Phillips suggests mental health professionals should be regularly screening to see if children have witnessed an arrest of someone they lived with and get them the help they need.
Data from the National Survey of Child and Adolescent Well-being was used to examine the experiences of children ages 8 and up who were suspected victims of child abuse and neglect.
The results are published online in the journal Children and Youth Services Review.
