Why do you say they were wrongly suspended? They were clearly in no danger from the man and could have just gone around him. And they failed to assist a citizen in serious distress, unconscious and bleeding from his head. A situation they caused, as it happens. The latter at least would seem to be a breach of their responsibilities as police officers.
... now charged and rightfully so! That said, I too am glad 57 others resigned. Anyone that supports what happened should not be serving.
