"There is no sane and intelligent person that reads these writings that think that this country should do away with the police or prisons."
Then you haven't read the writings of the sane and intelligent people that point out, for example, that the police, as currently understood, are an under-resourced department that is part enforcer of laws, part social worker (with varying degrees of success), part mental health expert (with varying degrees of success), and many others besides. Nor have you read the articles that talk about the absurdity of some of the rules under which police forces have to operate (which is why Chauvin will probably not be jailed).
Doing away with the police is simply the pragmatic response to resolving the issues around an institution that has devolved so far from what it is supposed to do that it is no longer fixable. The police are not supposed to be a quasi-military force with cultures that protect the handful of racists that join and invariably rise to the top. That is not to say that there won't be enforcers of laws, social workers and mental health workers after that, just that these roles would and should be carried out by individuals suited to them and the latter two (along with a lot of support for the poor and vulnerable) should be deployed to stop situations escalating to the point where the enforcers of laws are necessary.
