Wouldn't it look MUCH better on the Argentinian 70s or otherwise police or secret service force...
... if they recruited morally GOOD people instead of violent criminals let alone folks like rapists and murderers (or even suspected ones as such) into their force, no matter how skilled they were at other matters? Does it not worry them that this will look bad on their image?
(Some of those individuals will be massively looked down upon in other departments and yet here... My God.)
