I'm not doctor but I believe she possibly exhibited signs of trauma shock, one symptom of which possibly includes feeling disconnected from their emotions.
I don't know her background or how much she has been exposed to this type of event, but sitting inches away from a friend who is suddenly and unexpectedly shot to death would have a tendency to put some folks into shock state.
Yeah, that’s possible too. One of the most surreal events I ever was part of was when I worked a fresh murder with the a guy shot right in front of his three year old.
Guy is snoring and drumming his heels, I am trying to hold his brains in, and I look up at the kid who has blood on him and not one iota of emotion. Not fear, not sadness, nothing.
Of course, dad had been in prison all his life so there was no emotional bond.
Is it fair to assume based on her statements and Facebook readiness that both were very suspicious and fearful of police?
Then they get stopped.
Then he appears to have placed an unholstered firearm basically on his lap, maybe under his shirt.
We need more facts. But I have more difficulty reconciling their behavior and her statements then the officer’s method of effecting the stop.
