If the hospital upper echelon are making these decisions, which in all likelihood they are, seems to me that people higher in the food chain than them would be the only people with clout enough to stop them from killing people/letting them die. Other than media exposure which of course won’t happen, other than Project Veritas. And protests outside the hospital, if they’re not arrested.
However, the FREEPER network ****CAN**** be very resourceful, connected, clever and powerful. The Dan Rather thing comes to mind. If anyone could do it, FREEPERS could do it--regardless of who has to be motivated, shamed into acting honorably.
