Prisons don't interact with the public in the same way as police, and its easier to bend/break rules out of the view of the public. Officers don't have this luxury. What they do have is self regulation and the ability to determine they have done no wrong... That's what privatizing them will end.
That said, I can say(for certain) that we wouldn't see those sort of outcomes, but we would definitely be in a better position to address those problems, through local elections and market competition.
This is what I have trouble with will there be sufficient competition? Take NYC for example, we're talking about 50,000 employees. Do you envision a scenario where nyc has multiple options for private policing? Are there currently enough companies that could handle this? If not how realistic is it that there ever would be?
I could see this working in smaller towns/municipalities just struggling to envision the logistics involved with bigger cities.




Absolutely.
