In a society like this there is no negotiation no discussion except to tell you that power can crush you any time they want - not only you your whole family and all people like you.

Society questions the police and their methods and the police say Do you want the criminals off the street or not?

I realize I will always be the poster child for police brutality but I can try to use that as a positive force for healing and restraint.

Confronted with the choice the American people would choose the policeman's truncheon over the anarchist's bomb.

Where there are too many policemen there is no liberty. Where there are too many soldiers there is no peace. Where there are too many lawyers there is no justice.

I made two movies before The Police had a hit record: I did Quadrophenia and a film called Radio On.
