You can bet your sweet behind that the moment police is reduced to zero, other power factors in any society will fill the vacuum, and not the kind you would like to fill it.
But who has spoken of eliminating the police? I'm talking about changing the whole system and re-educating people, and that a system based on intimidation, privilege and fear is not healthy. In Spain there was a fascist dictatorship that ended 40 years ago, today some remnants of these ideologies are still being eliminated / changed in some corps authorities and elements of the state.
Because,you know,nazism and fascism was bad for the world and that.
Unfortunately you cannot do the same with the population, since almost half continue to remember the stupid and cartoonish element that motivated the use of the term Francoism, in the more stale Spanish style (I don't know if this is spelled correctly) to disguise its clearly fascist ideology. , stupid francisco Franco.
But you can change these things little by little, making people understand that there are other alternatives if we want to progress as a species or human beings.
However if for years you only promote hatred, superiority , towards other races, ideologies ... repeating the same rubbish speech, you get what you have,and it's reaching its lowest point.
Just to give you an example, I would like to know how many Americans knew the real C ism(I am not allowed to write the word) or if they have ever even seen one up close. It is hilarious your hatred for something based on repeated lies billions* of times.
