Firstly I respect individual police and you should too. Secondly I mean only to point out the possible legitimate origins of these sentiments, not to cast legitimacy to all such statements, especially where violence is concerned. Anyone who does attempt to legitimize violence is lying, for no one can. I cannot cast a swathe of certainty to justify these statements, only point out they are sometimes legitimate and even profound. To understand why the rhetorical respect these statements demand, let me take you on a walk down the Avenue of America to the essence of our national identity.
Institutions are not individuals. World history is a story of the interplay between man and machine, individuals and institutions. The United States designed the core of its justice system to uphold the individual among institutions, to empower the individual no matter guilt or innocence. Not to protect guilty people among innocent machines, but to allow innocent people to protect themselves from all machines, even corrupt powerful authorities.
Power corrupts, when people are making money off of jailing people there is guaranteed to be corruption. The founding fathers certainly shared the sentiment of f@#$ the police, no matter how they termed it.
Institutions are not individuals. Police oversee individuals. The police might be able to help you if individuals attack you in some way. Police can definitely help institutions if they are attacked by individuals in some way. Police can take action on individuals, but police cannot protect the individual from institutions. The police cannot do anything for you if institutions are destroying the environment of individuals let's say. It takes some complicated endeavor by special authorities to investigate trespasses of institutions against individuals. In the ghetto cops don't even protect individuals from individuals and institutions roll over people all over.
Institutions are not individuals. Individuals deserve respect, but machines are not alive and have no heart, which is sometimes broadly obvious. Gandhi knew this and had his own stop snitching campaign. Gandhi pressed people to not press charges in the English Courts and once after being physically attacked refused to press charges on his assailants, boycotting the corrupt system designed to keep people down, in caste.
So really I could care less what some representative of Big Brother might say, or authorities who protect institutions and serve individuals. I take my lessons from individuals like the founding fathers and Gandhi who always resented authorities of the corrupt status quo, people who always uplifted the individual among institutions. Institutions are simply tools, usually designed to benefit the few in some oligarchical and pyramidal fashion. F#@$ the police is not quite accurate to me. F#@$ the institutions. There that's better.
