I think this falls into better education of the public, many times these incidents arise because people try to argue their case with the officer but the officer is not the judge nor the jury. Trying to argue your case with a belligerent officer is only going to serve their purpose. Whereas if people know that have an absolute right to remain silent and exercise that right, they will be better served, especially if the officer is issuing unlawful orders / abusing power. If the officer thinks you are guilty, you cannot talk your way out of jail, but you can certainly give them more ammo to charge you with. e.g Resisting, Obstruction charges.
