How many police officers, doctors, phramacy workers, CEOs, Mayors, safety managers, nurses, volunteer jabbers, ect. are gonna choose the easy way out once they realise "I was just doing my job" is not an adequate defense for crimes against humanity?
A lot, they are inherently weak people.
Getting called a hero, and given free donuts and coffee for just following orders is some of their entire identity. Why do you suppose there's National Guard in every hospital in the country right now? Are they there to protect them when all the people that have been duped for the last 2 years realize what's been happening or there to arrest them?
Quite possibly both.
