As a doctor rounding in the hospital, I see a lot of sick patients. And when things go south, and people’s lives are hanging by a thread, the first staff to react are the nurses. Especially in the intensive care unit, at a moment’s notice, the nurses will be doing CPR, giving lifesaving medicines and comforting family members. These ICU nurses just want to help others, and that is exactly what Alex Pretti was doing when he was needlessly killed by federal agents.
