I am just average white US citizen who was working on oil rigs but most likely some of my whatsapp/facebook/iMessage contacts were related to families involved in dissidence against the Saudi government (because the oil region of Saudi is populated by a minority Shia group that is severely underrepresented in governance). Their mosques also had individuals with mental health issues who occasionally try to bomb the mosques in a very, very similar parallel to school shooters back home here in USA.
