Well, obviously. But it is very rare that you will get your theoretical rights when your legal opponent is a cop. One of the cases linked in the article literally had a camera running when a cop assaulted them[1], and yet they got charged for assult and resisting arrest first, dragged through court for a year while the prosecutors office refused to prosecute the police offer due to "lack of public interest, slim chance of guilty verdict and low degree of guilt". They look out for each other.
