SWAT teams and police cleared the building office by office. The White House never publicly addressed the attack of its own public health agency. I have spent 31 years in public health, long enough to watch trust in institutions like CDC erode gradually, then sharply, through Covid-19. Colleagues and I wrote last year that the agency had become “a public health agency in critical condition”; months later, a colleague and I described how antivaccine rhetoric was moving as fast as the virus itself. CDC was built to respond to the world’s threats, and as made real by the shooting, the agency now remains the target of threats.
