Numerous media reports (including NYT and WP) reported she died at at a local hospital after being transported there by ambulance. You may question that, too. I wonder whether she was DOA and pronounced dead after arrival or was still hanging onto life and died in the hospital, but that really does not matter.
You are welcome to believe what you believe. I understand trust in the media and our institutions has broken down, and for good reason. I sympathize with your distrust. I happen to believe she is dead. It’s a free country, and we are both free to believe what we believe.
Did you watch the video? The gun wasn’t even pointed at her.
