Cliff notes:
1. They were authorized for a no-knock, HOWEVER once Intel showed Glover (the violent offender that was the reason for the no-knock) wasn't going to be at the address, they knocked and announced several times (per the interview approximately 1 minute)
2. Taylor was being used by Glover to hold drugs and money and she was a knowing participant in the illegal activity
3.Shooter waited approximately 20mins to surrender, making it impossible to provide care to Taylor
4. Politicians who knew the facts withheld them to further a specific narrative.
