I knew a protester once who hated the police - once said in my presence (DH was a cop) that all the 'filth' deserved to die etc. etc.
Then he went to a protest in the States, got roughed up (not severely), was put in a jail cell without being formally charged, was released 2 days later, tried to leave the country, was detained at the airport, shouted back at the police there, got roughed up again, was detained for a further couple of days, and finally came back to the UK where he now has nothing but praise for the UK police 
Obviously some police are a not great. Same as doctors, nurses, teachers, plumbers, stylists, dentists, farmers and poets.
OP you are most unpleasant, and not terribly bright.
