I'm a Veteran with PTSD who experienced gun violence.
My mobile phone should tell Emergency call takers my location and that I have PTSD, so I might not be in my right mind if I heard gunshots or fireworks. This way my unusual reactions are explained.
Once a guy held a gun to my head at a bar. As I was calmly telling him that I would not beg for my life, a girl in there risked her life and called the Police.
This silent SOS will protect me, my daughter and bystanders, as calling the Police to report someone these days really can get you killed.
