King (Martin, not Rodney) said[1] "[a]ll we say to America is to be true to what you said on paper".
Kennedy suggested[2] a world "where the strong are just and the weak secure and the peace preserved".
If he were alive today, I'm sure JFK would have half a mind to ask "how could you elect such a schoolyahd president?"

My point was that in many cases, the police are not even making it up to that standard. They are breaking the law and their own rules in order to punish the protesters for daring to challenge their (the police's) perceived right to be above the law.
