It is important to not the latter did not mitigating police brutality as a public health interest, but racism in general.
From the letter:
> White supremacy is a lethal public health issue that predates and contributes to COVID-19. Black people are twice as likely to be killed by police compared to white people, but the effects of racism are far more pervasive. Black people suffer from dramatic health disparities in life expectancy, maternal and infant mortality, chronic medical conditions, and outcomes from acute illnesses like myocardial infarction and sepsis. Biological determinants are insufficient to explain these disparities. They result from long-standing systems of oppression and bias which have subjected people of color to discrimination in the healthcare setting, decreased access to medical care and healthy food, unsafe working conditions, mass incarceration, exposure to pollution and noise, and the toxic effects of stress. Black people are also more likely to develop COVID-19. Black people with COVID-19 are diagnosed later in the disease course and have a higher rate of hospitalization, mechanical ventilation, and death. COVID-19 among Black patients is yet another lethal manifestation of white supremacy. In addressing demonstrations against white supremacy, our first statement must be one of unwavering support for those who would dismantle, uproot, or reform racist institutions.
The remainder of the letter goes into strategies for mitigating the spread of COVID-19 during protests.
