Still reading through the Nova Gente interview...
This was the bit I'd remembered about his view on the hierarchy of his rights versus any administrative infringement:
I am a free man, and like any other citizen in this country, I have the right to express my opinions. I was a Criminal Investigation coordinator, a policeman, and there is no reserve duty, a functional or merely instrumental thing, from the exercise of a profession, that superimposes a fundamental right and freedom of expression. To state that the duty of reserve limits freedom of expression for life, or even during the exercise of the profession of policeman, is to elevate that duty, which is merely administrative, above freedom of expression and fundamental rights, consecrated in the Constitution of the Portuguese Republic, in the Universal Declaration of Human Rights and on the European Convention of Human Rights.
I think I can see a few problems with that argument...
